If temperature decreases in a reaction what type can it be?
Answer and explanation
Correct answer: Endothermic
If the surroundings become cooler during a reaction, the reaction may be absorbing heat from them. A reaction that takes in heat is called endothermic, so option A is the best answer. An exothermic reaction releases heat and generally warms its surroundings. Combustion is a particular type of usually exothermic reaction, while rusting is a specific slow oxidation process; neither term directly describes heat absorption.
