When energy (in this case, heat) is added, it excites the molecules and causes them to begin to move more. This extra movement causes them to repel one another more, causing the substance to take up more space.

Cold air has more molecules occupying a cubic centimeter of space then warm air therefore it has a what pressure?

Cold air has more molecules occupying space than warm air, therefore it has high pressure.


How do you explain when a state of matter is said to have definite volume?

A liquid or solid will not take up a larger space than the space it occupies; even if more space is freely available.On the other hand, both a liquid and a solid are incompressible, for most practical purposes; that is, you can't compress it to use less space than the space it uses, either.A liquid or solid will not take up a larger space than the space it occupies; even if more space is freely available.On the other hand, both a liquid and a solid are incompressible, for most practical purposes; that is, you can't compress it to use less space than the space it uses, either.A liquid or solid will not take up a larger space than the space it occupies; even if more space is freely available.On the other hand, both a liquid and a solid are incompressible, for most practical purposes; that is, you can't compress it to use less space than the space it uses, either.A liquid or solid will not take up a larger space than the space it occupies; even if more space is freely available.On the other hand, both a liquid and a solid are incompressible, for most practical purposes; that is, you can't compress it to use less space than the space it uses, either.

Does it take more energy to heat cold water to 212 F than it does to change 212 F water to steam?

yes. it do.


Which has more mass an ounce of feathers or ounce of gold?

An ounce of gold will have more mass because mass is how much space an object takes up. Feathers have a low density, while gold has a high density and takes up more space than a pourus (wispy) feather. So an ounce of gold does take up more space than an ounce of feathers.

Are cold air masses denser than warm air masses?

Yes, cold air masses are denser than warm air masses. The reason for this is because heat excites atoms so they take up more volume in space. Meaning they take up more volume of heat which leaves little warmth left and a lot of cold left. The warmth is thinner and vice versa, the cold is denser.

Why warm water is heavy than cold water?

Warm water is not heavier than cold water. Warm water is lighter than cold water because water, like most other materials, expands when heated causing it to take up more space while weighing the same amount (it becomes less dense).

Why does a kilogram of sand take up less space than a kilogram of feathers?

because sand is smaller than feathers and it would take up as much space with the sand , and if the feathers were there it would take up more space because its and larger object than the sand .
