Fun with a helium balloon A loosely filled balloon contains 4.5 liters of helium gas at atmospheric pressure (PA = 101 kPa) and room temperature T = 20 C. The gas in the balloon is then heated to body temperature, 37 C, by a student. (a) The pressure inside the balloon changes very little during the heating process. What is the change in the volume of the balloon? (b) How much work does the expanding balloon do on its environment?...

Now consider a more standard process: an isothermal expansion where the gas expands at ?=273K from ?i=1m3 to ?f=2m3. The initial pressure is ?i=1atm. E. In problem 1 of the week 2 written homework, the area under the PV diagram for this process is given by ??B? ln(V2/V1). Use this to compute the work done on the gas during this process. F. Compute the change in Gibbs free energy of the gas during this isothermal expansion. (Hint: How much heat...

I have filled in two glass gas bulbs with the same pressure of two different gasses: hydrogen gas (H2) and propane gas (CH,CH,CH3). The gas bulbs have the same volume and are also kept at the same temperature. Which of the two bulbs contains more molecules of gas? Select one: a. The bulb filled with propane contains more molecules, because propane has a greater molar mass than hydrogen b. The bulb filled with propane contains more molecules, because one propane...

Suppose that 292 moles of a monatomic ideal gas is initially contained in a piston with a volume of 1.34 m3 at a temperature of 588 K. The piston is connected to a hot reservoir with a temperature of 1385 K and a cold reservoir with a temperature of 588 K. The gas undergoes a quasi-static Stirling cycle with the following steps: The temperature of the gas is increased to 1385 K while maintaining a constant volume. The volume of...
