Heat of Fusion Formula The enthalpy of fusion equation shows that the amount of heat used in causing a phase change is divided by the mass of the matter that is changing phases. {eq}L_f = \frac{Q}{m} {/eq} Where {eq}L_f {/eq} is the heat of fusion, Q is the amount of ...
What is the formula for specific heat capacity? Heat Transfer: In physics, the heat transfer is the part of the energy transfer, where the energy transferred from a higher source to the lower source. To the transferred of energy from a lower source to the higher source, there is a need ...
The heat of vaporization, alternatively known as the enthalpy of vaporization, is simply the amount of energy needed to transition a specific amount of liquid to vapor. The enthalpy of evaporation is a function of temperature; it declines as the temperature increases and diminishes completely when ...
