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.) The average kinetic energy of the molecules of an ideal gas at 10°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? Express the temperature to the nearest integer. ► View Available Hint(s) T₁ = Submit Part B ——| ΑΣΦ 1 www. ? °C The molecules in an ideal gas at 10°C have a root-mean-square (rms) speed Urms. At what temperature T₂ (in degrees Celsius) will the molecules have twice the rms speed, 2vrms?
