What is an exothermic process?

Answer 1

An exothermic change is a change that releases heat. Combustion

is an exothermic chemical reaction.Adding water to sulfuric acid releases

heat, called exothermic heat of mixing.

Exothermic changes are the opposite of endothermic changes that

absorb heat when they take place.

Answer 2

An exothermic process releases heat to its surroundings during the reaction. This results in a decrease in the system's internal energy and an increase in the temperature of the surroundings. Examples include combustion reactions and many types of chemical reactions.

Answer 3

A chemical reaction or a physical phenomenon with release of heat.

Answer 4

When energy (heat) is lost from the system

Answer 5

Exothermic changes are types of changes that occur during a chemical reaction. These particular changes have occurred when chemical reactions have expelled heat or energy.

Answer 6

Not necessarily. Although many chemical processes are exothermic a number of physical processes, such a freezing and boiling, are also exothermic.
