32. A perfect gas expands polytropically with an initial volume and temperature of 0.06 m3 and 147°C. If the final volume and temperature are 0.21 m3 and 21°C, what is the value of polytropic index n?

Calculate the mass of air (in kg) contained within a room 10 m long, 8 m wide, and 3 m high. Assumeatmospheric pressure and temperature of 79,501 N/m2 and 20°C, respectively.

Six grams of helium(4.0026 g/mol) undergoes an Isothermal process at 127 Celsius, beginning at 6 atm. Their container was found to be 0.04 meters under cube after the expansion. Assuming that helium unit is an ideal gas, calculate the amount of keep that flowed into or out of the helium during the process.

A typical gasoline (β=0.00095/°C)  tank can hold 65 liters (~17 gallons). At the gas station, the storage tank is underground and is maintained at a temperature of 50.0°F. On a hot day at 103.0°F you fill your empty tank. (a) What is the equivalent temperature difference in °C? A typical gasoline (β=0.00095/°C)  tank can hold 65 liters (~17 gallons). At the gas station, the storage tank is underground and is maintained at a temperature of 50.0°F. On a hot day at 103.0°F you fill your empty tank. (c) How much gas should you put in your car on this hot day at so that it will fill (not overfill) the tank when it expands to 103.0°F?
