Thermodynamics is a branch of physics that deals with the study of energy and its transformations in various systems, including heat and work.
The first law states that energy cannot be created or destroyed, only transferred or converted from one form to another. The second law states that the total entropy of a closed system always increases over time. The third law states that the entropy of a perfect crystal at absolute zero temperature is zero.
Thermodynamics is relevant in everyday life as it explains how energy is used and transformed in various processes, such as cooking, driving a car, and even the functioning of our bodies.
Heat is a form of energy that is transferred between systems due to a temperature difference. Temperature, on the other hand, is a measure of the average kinetic energy of the particles in a system.
There are four types of thermodynamic processes: isothermal (constant temperature), adiabatic (no heat exchange), isobaric (constant pressure), and isochoric (constant volume). These processes are used to describe the changes in a system's properties as it undergoes a transformation.
