What happens as a gas' kinetic energy increases according to Gay-Lussac's law?

When a gas's kinetic energy increases, it directly affects the behavior of the gas particles. According to Gay-Lussac's law, if the temperature of an ideal gas increases, the pressure exerted by the gas in a constant volume is also expected to increase. This is because the kinetic energy of the particles is related to their temperature; as the kinetic energy increases, the particles move faster and collide with the walls of their container more frequently and with greater force.

As a result, a greater number of energetic collisions increases the pressure exerted on the container's walls. This relationship illustrates how the kinetic energy of gas particles correlates with temperature and pressure, reinforcing the principles of gas behavior in thermodynamic contexts.

In contrast, the other options involve scenarios that do not align with the principles explained by Gay-Lussac's law, such as expansion or phase changes, which do not correspond to a simple increase in kinetic energy under constant volume conditions.
