Question

explain briefly about thermal equllibrium....pls guys​

Answer 1

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.

The condition under which two substances in physical contact with each other exchange no heat energy. Two substances in thermal equilibrium are said to be at the same temperature. See also thermodynamics.

For example, a cup of water sitting on your desk, defined by the center 50% of its volume is very likely in thermal equilibrium.

Answer 2

Development of a thermal equilibrium in a closed system over time through a heat flow that levels out temperature differences . Two physical system are in thermal equilibrium if there is no net flow of thermal energy between them when they are energy between them when they are connected by a path permeable to heat..
