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. What is the algebraic expression for pressure in terms of V_1, T_1, p_1, V_3 and T_3 P3 = What is the pressure? P3 = kPa
