The air cylinder is connected to three identical vessels from which air is pumped out. How will the pressure in the cylinder change if the process took place at a constant temperature, and the volume of each vessel is equal to the volume of the cylinder?
To find the change in pressure in the original air cylinder, we use the formula: Pn * V1 = Pk * V2, from where we express: Pk = Pn * V1 / V2.
Variable ratios: V2 (final volume, volume of 4 cylinders) = 4V1 (initial volume, volume of one cylinder).
Calculation: Pk = Pn * V1 / V2 = Pn * V1 / 4V1 = Pn / 4.
Answer: The air pressure in the original cylinder will decrease by 4 times.
