Which of the following causes the pressure of a gas to increase? Adding more gas to create more collisions with the container wall Cooling particles down by decreasing the temperature Removing Q_(2) to slow the particles down Increasing the size of the container

The correct answer is: Adding more gas to create more collisions with the container wall.<br /><br />Explanation: According to the kinetic theory of gases, the pressure of a gas is caused by collisions of gas particles with the walls of the container gas is added to the container, there are more gas particles present, leading to an increase in the number of collisions with the container walls. This results in an increase in the pressure of the gas.
