The cylinder contains gas at a temperature of 27 degrees by how many times the gas pressure

The cylinder contains gas at a temperature of 27 degrees by how many times the gas pressure will decrease if 50% of it comes out of the cylinder, and the temperature will increase to 600K.

According to the Mendeleev-Clapeyron equation, the gas pressure is:

P = n * R * T / V, where n is the amount of gas substance, R is the gas constant, T is the temperature (in Kelvin), V is the volume.

According to the conditions of the problem, n2 = 0.5 n1, T1 = 27 0C = 300 K

P2 / P1 = (n2 * R * T2 / V) / (n1 * R * T1 / V) = (0.5 * 600) / (1 * 300) = 1.

The gas pressure will not change under these conditions.
