Why does heat capacity change with temperature?

Answer:

Heat capacity is a physical property that is constant for a specific matter and therefore, it is constant and will not change with temperature.

Explanation:

Heat capacity by definition is the amount of heat needed to increase the temperature of one gram (specific heat capacity) or one mole (molar heat capacity) by on degree (#1^@C#).

Therefore, heat capacity is a physical property that is constant for a specific matter and therefore, it is constant and will not change with temperature.

However, what changes is the amount of heat, which is represented by:

#q=mxxsxxDeltaT#

where, #q# is the amount of heat,
#s# is the specific heat capacity,
#DeltaT# is the change on temperature.
