Question: What happens to the pressure of a real gas as the temperature decreases at constant volume?

Options:

Correct Answer: Pressure decreases

Solution:

As the temperature decreases at constant volume, the kinetic energy of the gas molecules decreases, leading to a decrease in pressure.

What happens to the pressure of a real gas as the temperature decreases at constant volume?

What happens to the pressure of a real gas as the temperature decreases at constant volume?

Step 1: Understand that a gas is made up of tiny particles (molecules) that are always moving.
Step 2: Know that the temperature of a gas is related to the speed of its molecules; higher temperature means faster molecules, and lower temperature means slower molecules.
Step 3: Recognize that pressure is caused by gas molecules hitting the walls of their container.
Step 4: When the temperature decreases, the molecules move slower, which means they hit the walls of the container less often and with less force.
Step 5: Since the volume of the container is constant, the decrease in the speed of the molecules leads to a decrease in pressure.

Gas Laws – Understanding the relationship between temperature, pressure, and volume in gases, particularly the ideal gas law.
Kinetic Molecular Theory – The theory that explains how the motion of gas molecules relates to temperature and pressure.
