this is a copy from Yahoo answers but totaly correct
When heat energy is added to a gas, the velocity of the gas molecules increases (greater kinetic energy of motion). The gas molecules collide with the walls of the container with more force and bounce off which results in a net force (or pressure) on the container walls. Unless the container volume is enlarged as the gas is heated the pressure of the gas must increase
Atmospheric pressure is caused by gravity pulling on the air around the earth. The entire weight of the atmosphere is acting on the earth, and that is what air pressure is.
Heat is an example of energy.
Any type of reaction, really. You could add heat or remove heat (thermal energy) to cause the matter to change phase. Also pressure can compress the matter into a new form.
Air is matter but heat is energy.
heat.
Heat does not have an atomic structure. It is a form of energy, not matter.
Thermal Energy
Energy, such as light, are not matter since they cannot be touched or felt.
Heat is needed for matter to change form eg: Melting, condensation, etc.
You can raise an object (potential energy), make it move (kinetic energy), or add heat to it (heat energy, a.k.a. thermal energy).
Yes. As an example, you can melt ice by adding heat energy.
anything that is energy, for example light, sound , and heat
You add or subtract heat. An example is ice turns to water(solid to liquid) then water to stem are water vapor(liquid to gas)
Thermal energy is energy that is related to heat and the temperature of matter.
Yes all matter does have some heat energy in it
yes the heat will flow threw, but not create energy
Heat is not a form of matter: it is a form of energy. Of course, Einstein famously proved the equivalence of matter and energy.
Air is matter but heat is energy.
No. Heat and light are forms of energy, not matter.
