## What is Heat and Mass Transfer?

Heat and mass transfer are two fundamental phenomena that occur in nature and engineering systems. Heat transfer is the process of energy transfer due to temperature difference between two bodies or regions. Mass transfer is the process of transport of matter due to concentration difference between two phases or regions.

Heat and mass transfer are closely related, as they often occur simultaneously and influence each other. For example, when water evaporates from a liquid surface, heat is transferred from the liquid to the vapor phase, while mass is transferred from the liquid to the vapor phase.

## Why is Heat and Mass Transfer Important?

Heat and mass transfer play a vital role in many engineering applications and technologies, such as power generation, refrigeration, air conditioning, combustion, heat exchangers, solar energy, biotechnology, microelectronics, aerospace and more. Understanding the principles and mechanisms of heat and mass transfer is essential for designing, analyzing and optimizing these systems.
