Which of the following changes to a system will NOT result in an increase in pressure?

Increasing the volume of the container will not result in an increase in pressure. According to Boyle's Law, for a given amount of gas at constant temperature, pressure and volume are inversely related. This means that if you increase the volume while keeping the temperature and the number of gas molecules constant, the pressure will decrease. When the volume expands, the gas molecules have more space to move around, leading to fewer collisions with the walls of the container per unit time, which results in lower pressure.

In contrast, raising the temperature increases the kinetic energy of the gas molecules, resulting in more frequent and forceful collisions with the walls of the container, which increases pressure. Decreasing the volume of the container forces gas molecules closer together, increasing the rate of collisions and thus increasing pressure. Adding more gas molecules increases the number of particles that collide with the walls of the container, also leading to an increase in pressure.
