The study of heat changes that accompany chemical reactions and phase changes.

Front

What is an exothermic reaction?

Back

A reaction that releases heat to its surroundings.

Front

What is an endothermic reaction?

Back

A reaction that absorbs heat from its surroundings.

Front

What is specific heat?

Back

The amount of heat required to raise the temperature of 1 gram of a substance by 1°C.

Front

What is the formula for calculating heat energy (q)?

Back

q = m * c * ΔT, where m is mass, c is specific heat, and ΔT is the change in temperature.
