What is the root mean square speed of gas molecules at a temperature T? (2021)
Step 1: Understand that the root mean square speed (v_rms) is a way to measure the average speed of gas molecules.
Step 2: Know the formula for calculating v_rms, which is v_rms = √(3RT/M).
Step 3: Identify the variables in the formula: R is the universal gas constant, T is the temperature in Kelvin, and M is the molar mass of the gas in kg/mol.
Step 4: Make sure you have the values for R, T, and M before using the formula.
Step 5: Plug the values of R, T, and M into the formula.
Step 6: Calculate the value inside the square root (3RT/M).
Step 7: Take the square root of the result from Step 6 to find v_rms.
