a. specific heat
b. heat transfer
c. change of state
d. melting point

Specific heat

Explanation:

Specific heat capacity is the amount of energy required to raise the temperature of 1 kilogram of a substance by 1 Kelvin. According to the formula for heat capacity,(H)

H = mc∆t where m is the mass of the object, c is the specific heat capacity and ∆t is the change in temperature.

Specific heat capacity (c) from the formula will be c = H/m∆t
