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.

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
