Question : Which of the following is a characteristic of an exothermic reaction:
Option 1: Release of heat
Option 2: Absorption of heat
Option 3: Doesn't involve any change in temperature
Option 4: None of the options is correct
Correct Answer: Release of heat
Solution : The correct option is the Release of heat.
Exothermic reactions are those in which the system releases heat into the environment. The temperature of the surroundings rises because they are absorbing heat from the system. Respiration and burning of candles are examples of exothermic reactions.
