D) compressing the gas
E) All of the above are ways to increase the pressure of a gas.

Question

Quizplus · Accepted Answer

All the options listed are ways to increase the pressure of a gas. Heating the gas increases its kinetic energy, causing the gas molecules to collide more frequently and with greater force against the container walls, thus increasing pressure. Decreasing the volume of the gas (by placing it into a smaller container) increases pressure due to the gas molecules being more confined and colliding more frequently against the container walls, as per Boyle's Law. Adding more gas molecules to the container increases the number of collisions against the container walls, thus increasing pressure. Compressing the gas effectively decreases its volume, leading to more frequent collisions of gas molecules against the container walls, thereby increasing pressure.
