Q1
What happens to the pressure of a real gas as the temperature decreases at constant volume?
Pressure increases
Pressure decreases
Pressure remains constant
Pressure fluctuates
As the temperature decreases at constant volume, the kinetic energy of the gas molecules decreases, leading to a decrease in pressure.

Q
Q: What happens to the pressure of a real gas as the temperature decreases at constant volume?
Solution: As the temperature decreases at constant volume, the kinetic energy of the gas molecules decreases, leading to a decrease in pressure.
Steps: 5
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.
