What would be the heat released when:

State whether the specific heat capacity of a substance remains the same when its state changes from solid to liquid.

A substance is in the solid from at 0^(@)C . The amount of heat added to this substance and its temperature is plotted in the graph . The specific heat capacity of the solid substance is 0.5 "cal"//"g"^(@)C . Specific heat capacity in the liquid state is -

A substance is in the solid from at 0^(@)C . The amount of heat added to this substance and its temperature is plotted in the graph . The specific heat capacity of the solid substance is 0.5 "cal"//"g"^(@)C . Latest heat capacity in melting process is -

A substance is in the solid from at 0^(@)C . The amount of heat added to this substance and its temperature is plotted in the graph . The specific heat capacity of the solid substance is 0.5 "cal//g"^(@)C . The mass of the substance is -

The amount of heat energy Q, used to heat up a substance depends on its mass m its specific heat capacity (s) and the change in temperature DeltaT of the substance. Using dimensional method, find the expression for s is ( Given that [S]=[L^2 T^(-2)K^(-1)] ) is
