Q. 3

If heat is supplied to a solid, its temperature.
A. must increase

B. may increase

C. may remain constant

D. may decrease

Answer :

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
