- Figure 11 shows an insulated cylinder fitted with a pressure gauge, a heating coil and a frictionless piston of cross-sectional area 100 cm2.
(Solved)
Figure 11 shows an insulated cylinder fitted with a pressure gauge, a heating coil and a frictionless piston of cross-sectional area 100 cm2.
While the piston is at position O, the pressure of the enclosed gas is 10 Ncm-2 at a temperature of 27oC. when a 10 kg mass is placed on the piston, it comes to rest at position A without the temperature of the gas.
(i) Determine the new reading on the pressure gauge.
(ii) State with a reason how the value obtained in (i) compares with the initial pressure.
