What is thermodynamics and what kinds of law with example

Question

Accepted Answer

Thermodynamics is the study of energy and its transformations. It involves laws like the first and second laws of thermodynamics.

Thermodynamics is the branch of physics that deals with the relationships between heat, work, and energy.
The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed, only transferred or transformed.
The second law of thermodynamics states that the entropy of an isolated system always increases over time.
An example of the first law is the conservation of energy in a car engine, where the chemical energy in fuel is converted into mechanical energy.
An example of the second law is the fact that heat always flows from a hotter object to a cooler object, never the other way around.

Accepted Answer

A certain amount of matter or a certain area is called a thermodynamic system, when it is isolated from all the things that affect it.  The surface that surrounds a thermodynamic system is called the boundary of the system.  Thermodynamic systems are classified into closed, open and isolated systems.
