1. Which of the following describes an endothermic process?
Releases heat into the surroundings
Absorbs heat from the surroundings
Maintains a constant temperature
Involves no energy change
2. An example of an exothermic reaction is:
Melting ice
Photosynthesis
Combustion of fuel
Evaporation of water
1. In an exothermic reaction, the products have higher energy than the reactants.
True
False
2. An endothermic process feels cold to the touch because it absorbs heat from its surroundings.
