3.0 moles of an ideal monatomic gas occupy a volume of m3 at a pressure of N/m2. The gas undergoes a quasi-static adiabatic compression until its volume is decreased to m3.
What is the temperature of the gas before it is compressed?
What is the temperature of the gas after it is compressed?
How much work is done on the gas during the compression?
What is the change in the internal energy of the gas?
2.0 moles of a monatomic ideal gas are compressed adiabatically and reversibly from a state where the pressure is 4.0 atm and the volume is 9.0 L to a state with a pressure of 2.0 atm.
Find the volume of the gas in its final state.
Find the temperature of the gas in its final state.
Find the work done by the gas in the process.
Find the change in internal energy in the process. Assume that the molar heat capacity at constant volume and that the molar heat capacity at constant pressure for the monatomic ideal gas in the conditions given.
An ideal monatomic gas at a temperature of 542 K expands adiabatically and reversibly to 4.00 times its volume. What is the gas’s final temperature?
