Questions & Step-by-Step Solutions

What is the root mean square speed of gas molecules in an ideal gas at temperature T?
  • Step 1: Understand that we want to find the root mean square speed of gas molecules in an ideal gas.
  • Step 2: Know that the formula for root mean square speed (v_rms) is v_rms = sqrt(3RT/M).
  • Step 3: Identify the variables in the formula: R is the 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 to use in the formula.
  • Step 5: Plug the values of R, T, and M into the formula.
  • Step 6: Calculate the value of 3RT/M first.
  • Step 7: Take the square root of the result from Step 6 to find v_rms.
