A sealed cylinder holds 2.4 grams of nitrogen (N2) gas. The temperature is initially -97°C and the rms speed of the molecules is initially vo. If you heat the gas until the rms speed of the molecules becomes 1.5vo, what will the final temperature (in °C) of the N2 be? [Assume the volume of the cylinder remains constant. The molar mass of N2 is 28 grams/mole.]
