Question

what is meant by thermal equilibrium

Answer 1

hey dear
here is your answer ☞

==============

⭐Two physical systems are in thermal equilibrium if there is no net flow of thermal energy between them when they are connected by a path permeable to heat. Thermal equilibrium obeys the zeroth law of thermodynamics ⭐

hope it helps ^_^

Answer 2

Answer:

Thermal equilibrium means that the net flow of thermal energy is zero. Two bodies come to be in thermal equilibrium when the temperature and pressure between equal amounts of those substances is equal.

It follows zeroeth law of thermodynamics. This is possible for two systems only when they are isolated and kept as a single system.
