What is the relationship between pressure and temperature in a pressurized gas?

The correct answer illustrates the relationship defined by the ideal gas law, which emphasizes that for a fixed amount of gas at constant volume, if the pressure of a gas increases, the temperature also increases. This is primarily due to the kinetic energy of the gas molecules; as pressure rises, it often results from the molecules moving more vigorously and colliding more frequently, thus raising the temperature.

In a pressurized system, when energy is added (for example, through heating), the temperature increases, leading to an increase in pressure if the volume is constrained. Conversely, reducing the temperature typically leads to a reduction in pressure under the same volume and amount of gas. Therefore, it is essential to understand that temperature and pressure are directly related under constant volume conditions, making the option that states increased pressure results in increased temperature accurate.
