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?
