Question

When temperature is gradually decreased the specific heat of substance is

Answer 1

the substance heats up, the average temperature of the molecules increases, so when they collide, they are more likely to impart enough energy to allow rotation and vibration to occur as the energy jumps to a higher state. ... With an increase in temperature the specific heat of water first decreases then increases.

Answer 2

Specific heat is a measure of the ability of the substance to absorb heat. ... As the substance heats up, the average kinetic energy of the molecules increases. The collisions impart enough energy to allow rotation to occur. Rotation then contributes to the internal energy and raises the specific heat.
