The equation to be used to calculate the heat release when solid melts is the enthalpy of melting. It is represented 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:
H = mc∆t (metal solid)
H = mLice + mc∆t (ice)
Explanation:
Heat capacity is the energy needed to change the state of a substance through the application of heat thereby causing rise in temperature of the object.
For a solid object e.g metal to melt, the equation used will be
H = mc∆t where;
m is the mass of the metal
c is the specific heat capacity of the metal
∆t is the change in temperature of the metal.
For solid object like ice, the equation to use to calculate the heat released when it melts is given as
H = m1Lice +m2c∆t where;
m1 is the mass of the ice and
Lice is the latent heat of fusion of ice
m2 is the mass of water (after melting)
c is the specific heat capacity of the water
∆t is the change in temperature of the water
Note that m1=m2 since the same mass of ice is the one that melts to water.
