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

∙ 13y agoWhen you add heat to an object you increase it's energy thus increasing it's mass; it's the oppisote with cold.
To improve on this answer, that is in fact completely false. Increasing its energy increases its VOLUME not its mass. And the same with cold. Removing energy decreases its VOLUME, not its mass.

When heat is absorbed is it a chemical change?
No. Rather released. As during the physical changes in the states of matter, there is breaking of bonds involved. Whenever bonds are broken, the atoms of that matter come closer and energy they give out is more as compared to energy taken while breaking bonds. Hence, Physical changes at the level of states of Matter are always Exothermic i.e. RELEASING HEAT.
What is the change of energy taken in?
endothermic change
Can energy be taken during a physical change?
no
What must be added or taken away for a change in the state of matter to occur?
I believe "heat"To change from one state of matter to another state of matter heat is added or taken away.I think that makes sense!
When heat is taken away from matter it loses energy and its temperature decreases?
yes
endothermic?
A reaction where energy is taken in.
Is a change in matter in which energy is taken as an endothermic change?
yes
What must be added or taken away in order for matter to changes states?
Energy must be added or taken away.
A change in matter in which energy is taken in is an endothermic change?
Its where heat is taken in in a reaction eg making a cake is an endothermic reaction as heat is taken in to start it ;)

What happens is energy is taken away from matter?
When thermal energy is taken away from matter particles move more slowly. When thermal energy is added to matter particles move faster.

What energy changes occur when a photograph is taken?
As per my knowledge, when a photograph is taken there is a complex change of CHEMICAL energy to LIGHT energy ..... (Hope this helps you..)
