It is impossible for something to have a negative heat capacity, as the definition of heat capacity is the heat required to raise the temperature of a substance by 1 degree. No material will lose heat trying to increase its temperature, meaning that you can never have a negative heat capacity.
What does a negative specific heat mean?
Negative heat capacity would mean that when a system loses energy, its temperature increases.
Can specific heat be negative for a metal?
The specific heat, c, is the amount of energy required to raise the temperature of one gram of the substance one Celsius degree. ... Since the metal is losing heat, TInitialmetal > TFinalmetal and Tmetal will be negative.
