What is an exothermic reaction?

Back

A reaction that releases heat to the surroundings.

Front

What is an endothermic reaction?

Back

A reaction that absorbs heat from the surroundings.

Front

Define enthalpy.

Back

The measure of heat content in a substance, often represented as ΔH.

Front

What is heat capacity?

Back

The amount of heat required to raise the temperature of an object by 1°C.

Front

What does ΔH_vap represent?

Back

The energy required for the phase change from liquid to gas (evaporation).

Front

What does ΔH_fus represent?

Back

The energy required for the phase change from solid to liquid (fusion).

Front

How is the heat released calculated in a combustion reaction?

Back

By using the stoichiometry of the reaction and the enthalpy change associated with it.
