The absolute temperature of one mole of an ideal gas increased by 2 times, and the volume decreased by 2 times. How did the gas pressure change?
For a constant mass of gas, the combined gas law p * V / T = const is valid, that is, the product of pressure and the volume that the gas occupies divided by its temperature is a constant. If the absolute temperature is increased by 2 times, then T1 = 2 * T, and the volume is reduced by 2 times V1 = V / 2. Substitute these values into the formula p1 * V1 / T1 = p1 * V / 2 * 2 * T = p1 * V / 4 * T and this value should not change, therefore, the pressure should increase by 4 times.
Answer: pressure increased by 4 times
