Gas rises in a closed container because it is less dense than the surrounding air.
Gas pressure in a closed system is caused by the constant collisions of gas molecules with the walls of the container. These collisions create a force that exerts pressure on the walls of the container. The more frequent and vigorous the collisions, the higher the gas pressure.
The volume and shape of a gas are determined by its volume and shape of its container.
When a liquid is placed in a closed container, molecules with sufficient energy can escape from the liquid and turn into gas. This process is called evaporation.
Gas pressure decreases when cooling down a closed container.

the particles of gas bouncing into the walls of the container.
Lowering the temperature will cause a decrease in gas pressure in a closed container.
To determine the gas pressure in a closed container, you can use a pressure gauge or a manometer. These devices measure the force exerted by the gas molecules on the walls of the container, which is directly related to the gas pressure. By using the readings from the pressure gauge or manometer, you can calculate the gas pressure in the closed container.

A balloon filled with a gas will rise or sink depending on the density of the gas inside compared to the surrounding air. If the gas inside is less dense than the surrounding air, the balloon will rise. If the gas inside is more dense, the balloon will sink.
Contact between the particles of a gas and walls of the container cause pressure in a closed container of gas.

Gas Pressure
A decrease in gas pressure in a closed container could be caused by a decrease in temperature, which reduces the average kinetic energy of the gas molecules, leading to fewer collisions with the container walls. It could also be caused by a leak in the container allowing gas to escape, or by a chemical reaction that consumes gas molecules.
