The gas volume was reduced by a factor of 2, and the temperature was increased by a factor of 1.5.

The gas volume was reduced by a factor of 2, and the temperature was increased by a factor of 1.5. How has the gas pressure changed?

Initial data: the gas volume was reduced by 2 times (V1 = 2V2); the gas temperature was increased 1.5 times (1.5T1 = T2).

If the thermal process took place at a constant amount of gas substance, then the change in gas pressure is determined from the equality: ν * R = P1 * V1 / T1 = P2 * V2 / T2.

P1 * 2V2 / T1 = P2 * V2 / 1.5T1.

2 * 1.5 * P1 = P2.

3P1 = P2.

Answer: The gas pressure has increased 3 times.
