Question: The pressure of an ideal gas is directly proportional to its temperature when: (2022)

Options:

Correct Answer: Volume is constant

Exam Year: 2022

Solution:

According to Gay-Lussac\'s law, the pressure of an ideal gas is directly proportional to its temperature when the volume is held constant.

The pressure of an ideal gas is directly proportional to its temperature when: (2022)

The pressure of an ideal gas is directly proportional to its temperature when: (2022)

Step 1: Understand what an ideal gas is. An ideal gas is a theoretical gas that follows certain laws perfectly.
Step 2: Learn about pressure. Pressure is the force that gas particles exert on the walls of their container.
Step 3: Learn about temperature. Temperature is a measure of how hot or cold something is, and it relates to the energy of gas particles.
Step 4: Know what it means for pressure to be directly proportional to temperature. This means that if the temperature increases, the pressure also increases, and vice versa.
Step 5: Understand Gay-Lussac's law. This law states that the pressure of a gas increases with temperature when the volume of the gas does not change.
Step 6: Remember that for Gay-Lussac's law to apply, the volume must be constant. This means the gas is in a fixed container.

Gay-Lussac's Law – This law states that the pressure of a given mass of gas is directly proportional to its absolute temperature when the volume is kept constant.
