Questions & Step-by-Step Solutions
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.
