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

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

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

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.

we need to know the time interval during which the force acts. impulse of force = momentum change
