Thermodynamics
Thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy.
In particular, it describes how thermal energy is converted to and from other forms of energy and how it affects matter.

✔️ Thermodynamics :-
It is the branch of Physical science that deals with the relationships between heat and temperature and other forms of energy such as work and radiation . In particular , it describes how thermal energy is converted to and from other forms of energy and how it affects matter.
✔️ The behaviour of these quantities is governed by the four laws of Thermodynamics which convey a quantitive description using measurable macroscopic physical quantities.
✔️The laws of Thermodynamics are :-
# Zeroth law of Thermodynamics :-
If two systems are each in thermal equilibrium with a third , they are also in thermal equilibrium with each other.
# First law of Thermodynamics :-
The internal Energy of an isolated sytem is Constant.
# Second law of Thermodynamics :-
Heat cannot spontaneously flow from a colder region to a hotter region.
# Third law of Thermodynamics :-
As a system approaches absolute zero , all processes cease and the entropy of the system approaches a minimum value.
