What causes pressure in a closed container of gas? an increase in the thickness of the container walls collisions between the particles of gas and the container walls an increase in the size of the particles of the gas

collisions between the particles of gas and the container walls

Explanation:

Pressure is defined as the force acting per unit area.

Thus the pressure increases as the force increases and area decreases.

The particles present in a gas have least inter molecular forces of attraction ad thus the particles are in constant motion. they keep on colliding with other particles and the walls of the container in which they are kept.

Pressure of the gas molecules is due to the bombardment of gas molecules with other gas molecules and the walls of the container.
