What is thermodynamics and what are the types. give example for each laws.

Question

Accepted Answer

Thermodynamics is the study of energy and its transformations in physical systems. There are four laws of thermodynamics.

First law of thermodynamics: Energy cannot be created or destroyed, only transferred or converted. Example: A car engine converting fuel into mechanical energy.
Second law of thermodynamics: The total entropy of an isolated system can never decrease over time. Example: Heat flowing from a hot object to a cold object.
Third law of thermodynamics: As temperature approaches absolute zero, the entropy of a system approaches a minimum value. Example: The behavior of atoms at extremely low temperatures.
Zeroth law of thermodynamics: If two systems are in thermal equilibrium with a third system, they are in thermal equilibrium with each other. Example: Using a thermometer to measure the temperature of two objects.
