In the kinetic theory of gases, which of the following quantities is directly proportional to the square of the speed of gas molecules?
Step 1: Understand that the kinetic theory of gases explains how gas molecules behave.
Step 2: Know that gas molecules are always moving and their speed can vary.
Step 3: Learn that the average kinetic energy of gas molecules is related to their speed.
Step 4: Remember that kinetic energy is calculated using the formula: KE = 1/2 mv^2, where m is mass and v is speed.
Step 5: Realize that since kinetic energy depends on the square of the speed (v^2), it means that kinetic energy is directly proportional to the square of the speed.
Step 6: Recognize that pressure in a gas is related to the average kinetic energy of the molecules.
Step 7: Conclude that pressure is also directly proportional to the square of the speed of gas molecules.
