Expert Solution
Introduction:
- The amount of heat that is needed to cause a phase change between solid and liquid is known as the latent heat of fusion. The latent heat of vaporization is the amount of heat needed to cause a phase change between liquid and gas.
- Since the heat transfer in the given situation takes place through conduction the rate of heat transfer will be given by,
Here k is the thermal conductivity of the material, A is the surface area, T1 and T2 are the temperatures, and d is the thickness across the material.
