Questions & Step-by-Step Solutions
If the RMS speed of a gas is 500 m/s, what is the speed of the gas molecules at 1/2 of the RMS speed?
Correct Answer: 250 m/s
Step 1: Identify the given RMS speed of the gas, which is 500 m/s.
Step 2: To find the speed at 1/2 of the RMS speed, divide the RMS speed by 2.
Step 3: Perform the calculation: 500 m/s divided by 2 equals 250 m/s.
Step 4: Conclude that the speed of the gas molecules at 1/2 of the RMS speed is 250 m/s.
RMS Speed – RMS (Root Mean Square) speed is a measure of the average speed of gas molecules in a system, calculated from the kinetic energy of the molecules.
