- Calculate the temperature of 4.00 moles of ideal gas at a pressure of 2.00 atm and a volume of 54.0 L. (Use 0.0821 L · atm/mol · K as the gas constant.)

- Determine what happens to the pressure of the above sample of ideal gas if the volume is halved and the temperature doubles.

A student states that if the volume of a sample of ideal gas increases to three times the original volume, and the pressure also increases to three times the original pressure, the temperature of the gas will remain unchanged.

- Explain why the student is incorrect.
- Determine the actual temperature of the ideal gas
