A pneumatic tube system is used in a hospital to quickly transport laboratory samples across the building. A cylindrical canister (radius r = 12.5 cm, mass m = 950 g) containing the sample is placed in a tube with roughly the same radius. The bottom of the tube is exposed to atmospheric pressure, but the portion of the tube above the canister is maintained at a slightly lower pressure, which sucks the canister into the tube.

The cylinder, which has a sensitively moving piston inside, is filled with V₁ = 0.93421 The temperature outside is T₁ = 8 °C and the air pressure is p₁ = 101 kPa The piston is quickly pressed into the cylinder, causing the volume in the cylinder to decrease to V3 = 0.2975 1 and the pressure to increase to p2 = 210 kPa. The piston is locked in place and the cylinder is immediately brought to the laboratory. After that, it happened that the gas temperature became same as the laboratory temperature of T3 = 22 °C Determine the gas pressure when the gas temperature has reached the final temperature of the laboratory.
