Question

Which equation would you use to calculate the heat released when a solid melts?

Answer 1

The equation to be used to calculate the heat release when solid melts is the enthalpy of fusion.

Step-by-step explanation:

The enthalpy of melting is also known as the enthalpy of fusion of a substance. It is also known as latent heat of fusion. It is the change of enthalpy resulting from providing energy, typically heat, to a specific quantity of the substance to change its state from a solid to a liquid, at constant pressure. The equation can be written as H = mCpT where H is the heat released after phase change, m is the mass of the substance, Cp is the specific heat capacity of the substance and T is the change in temperature.

Answer 2

Answer and explanation;

The energy change of a melting solid is called the enthalpy of melting.

Therefore, the equation that can be used to calculate the heat released when a solid melts will be represented by;

H= mCΔT; where;

H is the heat released when solid melts and changes state

m is the mass of the solid substance

C is the specific heat capacity of the substance and

ΔT is the change in temperature
