    A flexible balloon contains 0.350 mol of an unknown polyatomic gas. Initially the balloon containing the gas has a volume of 6900 cm3 and a temperature of 30.0 ∘C. The gas first expands isobarically until the volume doubles. Then it expands adiabatically until the temperature returns to its initial value. Assume that the gas may be treated as an ideal gas with Cp=33.26J/mol⋅K and γ=4/3. What is the total heat Q supplied to the gas in the process? What is...

    1. Ideal Gas. A volume V = 0.1 m3 contains n = 5 moles of gas. Calculate the pressure (in N/m2) when the temperature T is 500 K. 5. Adiabatic Process. The same gas starts as it does in Problem 1. This time, the gas is allowed to expand to V2 = 0.25 m3 in an adiabatic way – no heat is allowed to transfer to or from the gas. Calculate the final pressure and temperature.
