When heat loss occurs from the result of a reaction, it is called an exothermic reaction (heat taken in is endothermic). the deffinition of heat is the average kenetic internal energy of what is "hot" or "cold". Heat is lost in the transition from g(gas) to l(liquid) g to s(solid) and l to s. and heat is absorbed from s to l, s to g, and l to g.

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!
Is solid the state of matter which is made when heat is taken away from a liquid?
Yes
When heat is taken away from matter it loses energy and its temperature decreases?
yes
What must be added or taken away in order for matter to changes states?
Energy must be added or taken away.
Is heat taken away or added in evaporation?
Taken away. As a liquid evaporates, it loses heat to the atmosphere.
Difference between sensible heat and latent heat?
Sensible heat is heat supplied or taken away and causes an immediate change in temperature without changing the state. While latent heat is heat supplied or taken away and causes a change in state without change in temperature. This difference can be applied to the certain properties of water/steam. This is called the thermodynamics properties of steam.
When heat is taken away from water it changes from a liquid to what?
Water changes to a solid, ice, when heat is taken away from it. You can think of putting water into the freezer. Since the freezer is cold, heat flows out of the water making it become ice cubes.
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 has to be taken away to turn ice into water?
heat
Is heat taken away or added in sublimation?
Sublimation is an endothermic physical change (heat is needed).
What happens to water when heat is taken away?
It becomes cold.
When heat is taken away what happens to the speed of the molecule?
It slows.
