A monatomic ideal gas (y = 5/3) is contained within a perfectly insulated cylinder that
is fitted with a movable piston. The initial pressure of the gas is 1.5 x 105 Pa. The piston is pushed so as to compress the gas, with the result that the Kelvin temperature doubles. What is the final pressure of the gas? a. 4.91 × 10° Pa b. 3.20 x 105 Pa c. 8.49 × 105 Pa d. 6.33 x 105 Pa

Question
One mole of a monatomic ideal gas undergoes a cycle that has four steps. At point 1 it starts at a pressure of 3 × 105 Pa and a volume of 20 × 10-3 m3 It undergoes an isothermal expansion to point 2 to a new volume at of 8.0 × 10-3 m?. It then undergoes an isochoric process to point 3 until its pressure is half as much of what it was at point 2. It then goes through an isothermal compression to point 4 to a volume of 20 mL. It returns to point 1 via an isochoric step.
What is the temperature of the gas at point 1?
How much work is done by the gas in step 1 to 2?
What is the pressure of the gas at point 2?
What is the total work done by the gas in the entire cycle?
