A at the start of a trip a driver adjusts the absolute, Ask an Expert

Academics

A.) At the start of a trip, a driver adjusts the absolute pressure in her tires to be 2.78E+5 Pa when the outdoor temperature is 287 K. At the end of the trip she measures the pressure to be 3.04E+5 Pa. Ignoring the expansion of the tires, find the air temperature (in K) inside the tires at the end of the trip.

B.) Initially, the translational rms speed of a molecule of an ideal gas is 460 m/s. The pressure and volume of this gas are kept constant, while the number of molecules is doubled. What is the final translational rms speed of the molecules?
