combustion
3
Q
explain how exothermic processes affect their surroundings
A
energy is transferred to the surroundings, so the temperature of the surroundings increases
4
Q
explain how endothermic processes affect their surroundings
A
energy is transferred from surroundings to reactants so the temp of surroundings decreases
