The dependent variable might be termed the "ordinate".
The dependent variable in an experiment is the data you are
When some variable depends on other variables, it is called the
dependent variable. For example, the temperature of something will
depend on how long you heat it, and th…
All companies that produce consumables must, by federal law, have an expiration date on it. Since bottled water is a consumable the company must put a expiration date on it.
Also some water becomes impure due to plastic melting or substances released into the water by the plastic.
How the Ship Gets Inside the Bottle
The ship is made in such a way that it will fit into the neck of an ordinary bottle. For example, if it is a sailing ship, the masts are made to hinge where they meet the hull so that they fold back, and the spars are rigged so that they swivel and lie flat. The r…
That question should probably be phrased differently. Gallons are a measure of volume. So are cubic inches and cubic feet. There are 231 cubic inches in one 1 gallon of fluid, and if that fluid is water, then it weighs 8.32 pounds. There is no such thing as a cubic gallon.Cubic is a term that implie…
The heart is closest to the brain, so when we walk it takes longer for the blood to get to our legs (that's why we exercise) and when we stand on our head the blood basically gushes to the brain. Your brain is saying "Whoa, what the heck is that!" Actually, it's healthy to stand on your head (in a Y…
Test tube babies are babies that are created in a test tube by
taking one sperm cell and one egg cell and combining them. So the
baby starts to develop in the test tube and is then implanted into
the mothers uterus.
You were pretty much right. Test tube babies are also called In
Vitro babies. I t…

0.4. The bond is considered to be n…
Traditionally a balance was used to measure mass. Objects of known or accepted mass was balanced against another object of unknown mass. When the balance was level the two pans had the same mass. The term balance or scales is still used even though there is no balance used. The scales were the pans …
Non-biodegradable can be misleading, as often the subject that this term is associated with is organic matter and organic matter always decays so it is biodegradable. This term was principally created to help improve public awareness of responsible recycling. Plastic is classed as non-biodegradable…
Science is a process of trying to determine the truth. Using the
scientific method, one investigates a question, conducts
experiments, and makes the results available for others to evaluate

A single ammonia producing process (for fertiliser) discovered by science is now responsible for feeding 40% of the worlds population. That is about 3 bil…
There are the two types of mixture systems, and the only similarity
between the two is that each has two or more components.
Homogeneous: These are mixture systems that are:
Uniformly (equally) distributed,
Miscible (will dissolve),
Of a single phase,
Easily dispersed through a membrane,
Very little for many vaccines. Vaccines are inexpensive to produce and many were never patented at all. Only a the newest ones are patented today.
The limitations of models in science are that they don't show you
the actual thing, models are very different.
The benefits of using models is the ability to get empirical data

1 Calorie per degree C. If room temp is 72 degrees C then 28
calories to get to boiling then the it takes 540 calories to water
from liquid to gas, called the heat of vaporization. So add 540 to
28 and you get 568 calories.
That's the energy to convert 1g of water at room temperature to 1g
Superstitious belief, by definition, have no scientific basis. Science requires that ideas are tested in a way that is repeatable and falsifiable. Falsifiable means that there must be a way that the test shows that a stated belief is not true, while most superstitions rely on metaphysical entities o…
Light entering a solution may pass entirely through or be absorbed partially or entirely depending on the solution concentration and the wavelength of the light. When this light is absorbed it transfers energy to the medium and can only hold the excess energy for about 10-5 seconds before it must re…
It is Latin for Under (Hypo) Heat (Caust) It was the Roman method of underfloor heating. A hypocaust (Latin hypocaustum, Greek hypocauston) was an ancient Roman system of underfloor heating, used to heat houses with hot air. The word derives from the Ancient Greek hypo meaning "under" and caust-, …
A capillary tube is used to carry a very small amount of blood. It is called a capillary (tube) because the movement in side is performed by "capillary action".
A experimental variable is good when you are trying to test an experiment. A variable may be easily controlled, isolated, and measured. For instance a difficult experimental variable may be a persons gender. You can control if a man or woman participates in your experiment, you may even easily ide…
Scientific models may be used to represent things that might be too
large or impossible to fit into one room. Globes, maps, and
drawings are used to represent the earth because we cannot fly into
space every time we need to look at it. We use models of atoms
because they are too small to see.
When non- polar molecules "shrink" from contact with water; they are considered hydrophobic. Hydrophobic means "water fearing", while polar molecules are hydrophilic, meaning "water loving".
Empirical is defined in the oxford dictionary as something based on

Standard atomic notation involves the Bohr-Rutherford diagram. This uses the number of protons, neutrons, and electrons, and also the mass number. You need to use the periodic table for the standard atomic notation. For example: 1- Mass # ( protons + neutrons) H -(hydrogen) 1- Atomic #( number o…
My first guess would be that they evaporate at the same speed, trick question.
My second guess would be that the leaves are higher, and there's much less water on the plant, so it would evaporate faster; that's not taking into account shaded areas.
To me, transpiration -is- evaporation, so it's …

The answer to this is subjective and therefore it cannot be
answered. Some people will agree with it and some people disagree.
Most people with a college education will agree with the scientific
explanation of the world. This may be in part based upon learning
the scientific attitude and processes.…
Yes. The water will evaporate and leave the residue of salt or sugar. A process crystalization is also there from which solids are purified from liquids by heating and then cooling, leaving purified crystalals.
Radio waves are reflected back to the Earth from the ionosphere.
Physical science is the study of matter and its behavior whereas biological science deals with the study of living tissue.
If you place a plastic cover over a cup of hot chocolate it stay
hotter longer because the heat is trapped in a material that
prevents it from escaping. For instance if you placed a tissue it

This is because science is not just the information presented (the product), but also the way in which that information has been collected (the process). While scientific knowledge should be testable and falsifiable (according to Karl Popper), the way in which such information has been gathered is a…
Yes, water vapor can act like a prism.A rainbow is caused by raindrops, not by vapor. When light enters a raindrop at an angle to its surface, different colors refract at different angles as in a prism. A reflection occurs at the far side of the drop, and more refraction occurs as the light exits th…
Moral science can serve as a guide to someone's life and provides a path for success in social activities and other tasks, goals, or actvities that impact both other people and the world.
Science without philosophy has no guide (is blind). It researches pointless things rather than what we want to know, like the origin of the universe and how to stop global warming. Philosophy without science has no substance (is empty): As an example, more than 2000 years ago, the Grecian philosophe…
This is a physical change.
To describe things as they truly are or behave, without any prejudice to force or "massage" or select observations to fit any preconceived ideas or notions about what you think should happen.
The light is scattered. Some of the light may be absorbed, depending on the surface.
Scientifically, work is defined as force X distance. In this case,
we know the distance (5 m), but we do not know the force. If we
knew the original force applied we could calculate the work done.
Or, if we knew the acceleration of the 2 kg mass when it was moved
we could calculate the force (force …
It is dangerous because of the dangerous gases that form from
polymers in the burning process. When polymers such as plastics are
burned carbon containing gases are released. During the burning
process, the carbon combines with oxygen present in the atmosphere
& forms oxides of carbon.
The 'popping' sound of a balloon disintegrating is made by the sudden expansion of air when the skin is damaged. The compressed air within is then able to escape. One interesting variant of your 'water' experiment, is to stick a bit of cellulose tape to the balloon, and then you'll find that you ma…

The definition of sublimation is when a material goes directly from
solid to gas phase, without melting first. If the material is
liquid and it transforms to gas, that's called evaporation (when
it's gradual at any temperature) or boiling (when it all starts to

Scientific laws are formed from repeated experimental observation and apply to like conditions identifying relationships of some type.An example of scientific laws of nature is the laws of heredity. These laws explain how genes are inherited, but do not explain how genes work.
Electromagnetic waves hit both the north ans south poles. These are
the same rays that hit the rest of the Earth. The difference is in
the angle at which they hit. They are more oblique than at the
equator, and so they get spread over a bigger area and so heating
is less intense.
Agricultural science is a broad multidisciplinary field that encompasses that parts of exact, natural, economic and social sciences that are used in the practice and understanding of agriculture. Agriscience- Is the application of scientific principles of agriculture.
