Hint: Latent heat can be defined as the heat or energy which is absorbed or released during a phase change of a substance. The phase change could either be from a gas to a liquid or liquid to solid and vice versa.
Complete answer:
Latent heat is related to a heat property called enthalpy and can also be defined as the work needed to overcome the attractive forces which hold molecules and atoms together in a substance.
Latent heat of vaporization can be defined as the total amount of heat required to convert the liquid state into vapor without increasing the temperature of that liquid or fluid i.e. that heat which changes the liquid state into gaseous state or we can say the heat consumed or discharged when matter disintegrates or changes state from liquid to gas state at a particular temperature.
Heat of vaporization can also be defined as the quantity of heat that needs to be absorbed to vaporize a particular quantity of liquid at a constant temperature. If the solutions of vapor and liquid states are compared then the kinetic energy of the steam is always comparatively higher than the kinetic energy of the fluid.
Based on entropy and enthalpy of vaporization and relationship between them heat of vaporization can be calculated by the following formula:
$\text{Q=2364}\text{.6}\times \text{25=59115J=59}\text{.1KJ}$
$H_v$= $\dfrac{q}{m}$
Where, $H_v$ represents the heat of vaporization, m is mass of substance and q is heat absorbed.
Note:
The heat of vaporization is characterized as the measure of heat expected to transform 1 g of a fluid into a fume without any change in the temperature of the fluid. The heat of vaporization is latent heat.
