The pressure exerted by a given mass of gas in a container
Question 1 Report
The pressure exerted by a given mass of gas in a container
Answer Details
The pressure exerted by a given mass of gas in a container increases if the molecules of the gas move faster.
Pressure is the force exerted by a gas per unit area of the container walls. The force that the gas molecules exert on the walls of the container is due to their constant random motion, or kinetic energy. When the gas molecules collide with the container walls, they transfer some of their kinetic energy to the walls, exerting a force that contributes to the overall pressure of the gas.
If the molecules of the gas move faster, they will collide with the container walls more frequently and with greater force, leading to an increase in pressure. Conversely, if the gas molecules move more slowly, they will collide with the container walls less frequently and with less force, leading to a decrease in pressure.
Therefore, answer is correct. The pressure exerted by a given mass of gas in a container increases if the molecules of the gas move faster.
