A particle gas consists of N monatomic particles each of mass m all contained in a volume V at temperature T. Your answers should be written in terms of the Boltzmann constant kB and Avagadro's number NA rather than R=NAkB. a. Express the pressure p of the gas in terms of its energy density U/V. Enter the numerical factor that multiplies U/V in your expression for p to at least three significant figures. b. What will be the ratio of the new molar mass M? to the old molar mass M?) c. What will be the ratio of the new rms speed v?rms to the old rms speed vrms? d. What will be the ratio of the new molar heat capacity C?V to the old molar heat capacity CV?

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
