it gets colder
particles
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!
It becomes cold.
It slows.
It contracts.
A mixture is formed and if any chemical reaction among these matters take place, either heat is evolved or taken in to form a new compound.
When thermal energy is taken away from matter particles move more slowly. When thermal energy is added to matter particles move faster.
When light falls on matter, it can be absorbed, reflected, or transmitted. Absorption occurs when the light energy is taken in by the matter and converted into heat. Reflection occurs when the light bounces off the surface of the matter. Transmission occurs when the light passes through the matter without being absorbed or reflected.
Yes
it gives off its gas and heat
An endothermic reaction need heat to occur.
Conduction is heat transfer WITHOUT matter transfer Convection is heat transfer WITH matter transfer
