Question

What do you mean by Equilibrium state in physics??

Answer 1

$\huge{\underline{\mathfrak{\ ANSWER}}}$

A physical equilibrium is a system whose physical state does not change when dynamic equilibrium is reached while in a chemical equilibrium chemical composition of the system does not change when dynamic equilibrium is reached.. Example of physical equilibrium: When a solid is heated it starts melting at a certain fixed temperature (melting point). At this stage even when the heating is continued, the temperature does not change until the whole of solid is converted into liquid.

The condition of equilibrium has two requirements:

All forces balance. This means that force vectors add to zero.

All torques balance around anypoint. This means that the sum of all clockwise and counterclockwise torques is zero.
