When doing numerical calculations involving temperature, you need to pay particular attention to the temperature scale you are using. In general, you should use the Kelvin scale (for which T=0 represents absolute zero) in such calculations. This is because the standard thermodynamic equations (i.e., the ideal gas law and the formula for energy of a gas in terms of temperature) assume that zero degrees represents absolute zero. If you are given temperatures measured in units other than kelvins, convert them to kelvins before plugging them into these equations. (You may then want to convert back into the initial temperature unit to give your answer.) A. The average kinetic energy of the molecules of an ideal gas at 10 degrees C has the value K10 . At what temperature T1 (in degrees Celsius) will the average kinetic energy of the same gas be twice this value, 2K10? B. The molecules in an ideal gas at 10 degrees C have a root-mean-square (rms) speed vrms . At what temperature T2 (in degrees Celsius) will the molecules have twice the rms speed, 2vrms ?
