1
Q
Describe an exothermic reaction
A
They transfer energy from reacting molecules to the surroundings
= the temperature of surroundings increases
2
Q
Example of exothermic reaction
A
Combustion
Oxidation
3
Q
Describe endothermic reactions
A
Take in energy from surroundings
= temp of surroundings decreases
4
Q
