Question

A 1.16 mol sample of Xe gas is confined in a 27.6 liter container at 17.1 °C If the amount of gas is increased to 1.74 mol, holding the volume and temperature constant, the pressure will increase because: Choose all that apply. 一with more molecules per unit volume, the molecules hit the walls of the container more often. O With higher average speeds, on average the molecules hit the walls of the container with more force. With more molecules in the container, the molecules have higher average speeds. e average speed increases, the number of molecule-wall collisions decreases As th None of the Above

Answer 1

The pressure will increase because with the more molecules per unit volume, the molecules hit the walls of the container more often. So, first option from the top is the right option.
