Question

what is thermal equilibrium?​

Answer 1

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

Answer 2

Answer:

Explanation:

Thermal Equilibrium

A system is said to be in thermal equilibrium when there is no tempreature difference between system and surroundings

• Thermal equilibrium means “Temperature gradient is zero”

• There is no heat flows between the objects.
• It’s obey the Zeroth law of thermodynamics.

Example

Suppose we have metal bar and is heated and then we keep it our in room (room temperature).

After sometime the bar will have same temperature at every point on it.

There is no gradient of temperature , No heat exchange between bar and surrounding.
