Part A A flexible balloon contains 0.360 mol of an unknown polyatomic gas. Initially the balloon containing the gas has a volume of 7200 cm 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 = 33.26 J/mol · K and y= 4/3. What is the total heat Q supplied to the gas in the process? View Available Hint(s) VAZO ? J Submit Part B What is the total change in the internal energy AU of the gas? View Available Hint(s) ΡΕΙ ΑΣφ ? AU =
