endothermic and exothermic Flashcards
1
Q
exothermic reactions
A
when energy is released into the surroundings and feels hot as a result. This happens when bonds are made. there is an increase in temperature but a decrease in energy.
2
Q
endothermic reactions
A
when energy is absorbed from there surroundings and feel cold as a result. They happen when bonds break. There is a decrease in temperature but increase in energy.
3
Q

A
gas to liquid to solid
