Can Heat Capacity Be Negative

Say you have an object with a negative heat capacity.

Can heat capacity be negative. I dont understand why this object cannot be in thermal equilbrium. A negative temperature can. If a system loses energy it can result in a negative delta T therefore negative heat capacity.

This means that the object increases in temperature as it radiates energy and decreases in temperature as it absorbs energy. Water is inserted which is. When equilibrium is reached the final temperature is 80 degrees C.

W are opposite in direction of heat flow gain or loss but does not indicate the arithmetic sign of either q value that is determined by whether the matter in question gains or loses heat per definition. The heat capacity in calories per gram is called specific heat. Specific heat capacity can never be negative because its an absolute property of the material No problem.

Negative heat capacity occurs in all systems having negative total energy. The magnitude of the heat change is therefore the same for both substances and the negative sign merely shows that q_substance. The molar specific heat capacity can be negative.

Hope this solves your query. Can specific heat be negative. What does a negative calorimeter constant mean.

When talking about the specific heat capacity of solids it has the units of. It is questionable however whether the total energy has to be counted as internal energy when. The question of the virial theorem and negative heat capacities a subject mentioned already is then addressed before the extension to open systems is discussed and it is noted that in open systems it is not prohibited for the heat capacity to assume a negative value.
