Thermal Equilibrium
- Two systems are said to be in thermal equilibrium if the temperatures of the two systems are equal.
- In mechanics if the net force on a system is zero, the system is in equilibrium.
- In Thermodynamics equilibrium means all the macroscopic variables (pressure, temperature and volume) don’t change with time. They are constant throughout.
For Example: -
- Consider two bodies at different temperatures one is at 300C and another at 600C then the heat will flow from body at higher temperature to the body at lower temperature.
- Heat will flow till both bodies acquire same temperature.
- This state when there is no heat flow between two bodies when they acquire the same temperature is known as thermal equilibrium.
