When the temperature of a gas increases, its pressure also increases, provided the volume of the gas remains constant. This relationship is described by Gay-Lussac's law, which states that the pressure of a gas is directly proportional to its absolute temperature (measured in Kelvin). Specifically, as the temperature rises, the kinetic energy of the gas molecules increases, causing them to move faster and collide with the walls of their container more forcefully. If we consider a fixed volume, this leads to an increase in pressure. For example, if a gas at 0°C (273 K) is heated to 100°C (373 K), the pressure will rise if the volume is held constant. This explanation incorporates key scientific principles and context, enhancing understanding of the behavior of gases under temperature changes.<|im_end|>

When you heat a gas, its pressure goes up. This is because heating makes the gas expand and push against the walls of its container. So, if you heat something up, it just gets more pressure.<|im_end|>
