Part B

A gas cylinder has a piston at one end that is moving outward at speed vpiston during an isobaric expansion of the gas. Find an expression for the rate at which vrms is changing.

Express your answer in terms of the variables vp, vr, and the instantaneous value L of the length of the cylinder.

Part C

A cylindrical sample chamber has a piston moving outward at 0.50 m/s during an isobaric expansion. The rms speed of the gas molecules is 450 m/s at the instant the chamber length is 1.5 m. At what rate is vrms changing?

Express your answer with the appropriate units.

dvrmsdt d v r m s d t =	nothing

nothing
