Fall in temperature during a chemical reaction may indicate what?
Answer and explanation
Correct answer: Absorption of heat
A fall in temperature during a reaction generally indicates that the reacting system is absorbing heat from its surroundings. Such a reaction is called endothermic. Therefore, option A is correct. Release of heat would usually raise the temperature, while light emission and rusting are possible reaction features but do not specifically explain a temperature decrease.
