Question

A 1.00 mol sample of O_2 gas is confined in a 23.7 liter container at 16.3 degree C If the amount of gas is increased to 1.50 mol. holding the volume and temperature constant, the pressure will increase because: With more molecules per unit volume, the molecules hit the walls of the container more often. With higher average speeds, on average the molecules hit the walls of the container with more force. As the number of molecule-wall collisions increases, the force per collision decreases. With more molecules in the container, the molecules have higher average speeds. None of the Above

Explanation / Answer

No of moles of gas is increased means there are more gas molecules and this will increase the number of impacts on the container walls.

Hence,

1 and 3 statements are true.
