The Q in the enthalpy of fusion equation stands for heat energy absorbed or released.
What is enthalpy?
In thermodynamics, enthalpy is a measure of the heat content of a chemical or physical system.
The enthalpy of fusion is the amount of heat energy required to convert a unit mass of a solid at its melting point into a liquid without an increase in temperature.
Its units are usually Joules per gram (J/g) or calories per gram (cal/g).
The enthalpy of fusion equation is given as follows:
Q = m·ΔHf
Where;
- Q = heat energy
- m = mass
- ΔHf = heat of fusion
Therefore, the Q in the enthalpy of fusion equation stands for heat energy absorbed or released.
