Question

A horizontal cylinder 60 cm long, closed at both ends, is divided into two equal parts by an insulated piston. Each half holds equal masses of gas at 27°C and 1 atm. One half is heated to 87°C. Find how far the piston moves, in cm (two decimals).

Equal final pressures: ( 30 + x ) / ( 30 − x ) = ( 360 ) / ( 300 ) , so x = 30 × ( 60 ) / ( 660 ) = 2.73 cm . The final pressure is ( 2 × 360 ) / ( 660 ) = 1.09 atm .
