Final answer:
Gay-Lussac's Law states that the pressure of a gas will increase if its temperature rises, and its volume remains constant. This is because pressure and temperature are directly proportional in a fixed volume. For instance, if a gas-filled balloon is heated without allowing expansion, the internal pressure would rise due to the temperature increase.
Step-by-step explanation:
According to Gay-Lussac's Law, the pressure of a gas is directly proportional to its absolute temperature (measured in Kelvin), provided the volume stays constant. This means that if the temperature of a gas increases while its volume remains unchanged, its pressure will also increase. For example, if you heat up a gas-filled balloon (without allowing it to expand), the pressure inside the balloon would increase due to the increase in the temperature.
