Question

observe the simulation that shows how changing the volume of the gas affects the pressure of the gas when the gas is kept at a constant temperature. select the correct statement(s). the particles of gas collide less often when the system has a lower volume. when particles collide more often, the pressure increases. when particles collide less often, the pressure increases. increasing the volume of the gas increases its pressure. the particles of the gas collide more often when the system has a lower volume. increasing the volume of the gas decreases its pressure.

Explanation:

According to the ideal gas law and kinetic - molecular theory of gases, when the volume of a gas decreases (system has a lower volume), gas particles have less space to move. So, they collide more often with the walls of the container, which increases the pressure. Conversely, when the volume of the gas increases, particles have more space, collide less often with the walls, and the pressure decreases.

Answer:

• The particles of the gas collide more often when the system has a lower volume. Increasing the volume of the gas decreases its pressure.
• When particles collide more often, the pressure increases. When particles collide less often, the pressure decreases.
