If heat is supplied to a solid, its temperature.
Heat transferred, ΔQ=mCΔT
Where,
ΔT=tempeature change
M=mass
C=heat capacity
Thus, form the above relation, we found that the heat capacity of an object is directly dependent on the temperature difference.
Hence, we can say that the when the heat is applied to the solid, temperature of the solid can be zero or positive so the temp will remain constant or will increase when heat is supplied
