Question

Quizplus · Accepted Answer

When a rigid, sealed box containing gas is heated from 25°C to 50°C, the volume and the moles of gas remain constant because the container's size and the amount of gas cannot change. However, the pressure inside the container increases due to the increase in temperature, as described by Gay-Lussac's law, which states that the pressure of a gas is directly proportional to its temperature when the volume and the amount of gas are held constant.
