yes
endothermic change
No, chemical reactions are not the only reactions that may involve absorption of energy. A physical change like heating water to vapor is also endothermic.
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.
Light energy
Water is taken in. Light energy is used
Vaporization is an endothermic process; evaporation is exothermic.
no, endothermic trust me it shows it in my book
no, endothermic trust me it shows it in my book
If energy is released as a result of a process, an exothermic change has taken place. If a constant input of energy is required to drive a physical or chemical change, the change is described as endothermic.
A reaction where energy is taken in.
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 ;)
When energy is added,solid will melt into liquid or liquid will change into gas. (When energy is added it gains heat).When energy is removed, the liquid will turn into solid or the gas will turn into liquid. (When energy is removed the heat will lose).

well, it depends on what you have and what you are using. it normally takes oxygen, carbon dioxide, and the other chemical you want to use hoped this helped <3
