Q1
According to the kinetic theory of gases, the pressure exerted by a gas is due to:
the gravitational force on the gas
the collisions of gas molecules with the walls of the container
the temperature of the gas
the volume of the gas
Questions & Step-by-Step Solutions
According to the kinetic theory of gases, the pressure exerted by a gas is due to:
Correct Answer: Collisions of gas molecules with the walls of the container.
Step 1: Understand that gases are made up of tiny particles called molecules.
Step 2: Know that these gas molecules are always moving around in random directions.
Step 3: Realize that when these moving gas molecules hit the walls of their container, they collide with it.
Step 4: Understand that each collision transfers a small amount of force (momentum) to the wall.
Step 5: Recognize that when many molecules collide with the walls, the total force from all these collisions creates pressure.
Step 6: Conclude that the pressure of the gas is the result of these continuous collisions of gas molecules with the walls.
Kinetic Theory of Gases – The theory that explains the behavior of gases in terms of the motion of their molecules, emphasizing that pressure results from molecular collisions with container walls.
