The gas temperature in the upper part of the vessel is equal to t. And at the bottom?

The gas temperature in the upper part of the vessel is equal to t. And at the bottom? In this case, the gas is in a state of thermal equilibrium in a closed vessel.

We will proceed from the fact that the gas is in a state of thermal equilibrium, therefore, its thermodynamic parameters do not change for a long time. You also need to know that in the lower part of the vessel, the temperature is also constant t (that is, it does not change).
Let’s write as: t = const.
