When thermal energy is taken away from matter particles move more slowly. When thermal energy is added to matter particles move faster.
What happens when thermal energy is taken away
Energy must be added or taken away.
When thermal energy is taken away from matter, the particles will lose energy and slow down, leading to a decrease in temperature. As the particles slow down, they may eventually come together and form a solid if enough energy is removed. This process is known as cooling or condensation.
The substance's particals will start slowing down and come closer together. As kinetic energy is removed from a substance, it will do the opposite as when kinetic energy is added to a substance.
It increases.
Then the matter will end up having less energy.Then the matter will end up having less energy.Then the matter will end up having less energy.Then the matter will end up having less energy.
Energy is neither created nor destroyed. The energy does not change, it may change form.
If enough energy is taken away from water vapour, it will condense to form water (in liquid form). This is because a gaseous state requires more energy than a liquid state (and a liquid state requires more energy than a solid state).
As energy is taken away from a substance, the particles within the substance slow down and lose kinetic energy. Eventually, the particles may form a solid structure as they come closer together due to the reduction of thermal energy.
Yes, when heat is removed from matter, the molecules within the matter lose kinetic energy, causing the temperature to decrease. This decrease in temperature can lead to phase changes, such as from a liquid to a solid or a gas to a liquid.
Energy is lost
Some chemical compounds change or dissociate when thermal energy is applied, and substances can melt or vaporise. Another cause for changing chemical substances is electrolysis due to applying electrical energy. I'm not sure if you meant this type of change when you ask 'is matter changed'. Matter could be taken to mean the elements concerned, and of course there is no change to the nuclear properties of the elements involved in the above changes. If nuclear energy is added however, as in a nuclear reactor or a bomb, then matter can be changed by the neutron irradiation that occurs in these processes
