The value of heat capacities!

Just a general question, could the value of heat capacities every be negative? For example, if we were to find the value of the specific heat capacity, and were given q = -1000 joules, mass = 100 grams, and change in temperature is +100 degrees celsius. The resulting specific heat capacity would be negative. Is this possible?

Negative heat capacities are not possible.

Think about the definition of heat capacity.
You just asked if the temperature of something can go up by 1oC when heat leaves it.
