Is it possible for a closed system in thermal equilibrium possesses two regions with different pressures supposing such regions had the same pressure in the past?
Thermal equilibrium refers to a state in which two systems that are in contact with each other have reached the same temperature and there is no net transfer of heat between them.
In thermal equilibrium, the pressure of the two systems will also be equal. This is because the particles in each system are moving at the same average speed, resulting in the same force being exerted on the walls of the container.
When thermal equilibrium is reached, the pressure of the two systems will be equalized. This means that if one system had a higher pressure initially, it will decrease to match the pressure of the other system.
As temperature increases, the average speed of particles in a system also increases. This results in more collisions between the particles and the walls of the container, leading to an increase in pressure.
No, two systems in thermal equilibrium must have equal pressures. If the pressures are different, then heat will continue to transfer between the systems until thermal equilibrium is reached and the pressures are equalized.
