A pneumatic lift consists of a vertical cylinder with aradius of 10.0 cm. A movable piston slides within the cylinder atits upper end and supports a platform on which loads are placed. Anintake valve allows compressed air from a tank to enter the cylinder,and an exhaust valve allows air to be removed from the cylinder. Ineither case the rate of air transfer is sufficiently low that the temperaturein the cylinder remains constant. When neither valve is activated,the cylinder is airtight. The piston and platform together have a massof 50.0 kg, the temperature is 20.0C, and the pressure outside thecylinder is 1.00 atm. At what rate should this air be introduced, in mmol/s, so that the platform rises at a rate of 10.0 cm/s?
