Question: A cylinder that has a 40 0 cm radius and is 50 0 cm deep
A cylinder that has a 40.0-cm radius and is 50.0 cm deep is filled with air at 20.0°C and 1.00 atm (Fig. P19.68a). A 20.0-kg piston is now lowered into the cylinder, compressing the air trapped inside (Fig. P19.68b). finally a 75.0-kg man stands on the piston, further compressing the air, which remains at 20°C (Fig. P19.68c) (a) How far down ("h) does the piston move when the man steps onto it? (b) To what temperature should the gas be heated to raise the piston and man back to hi?
