Asmall well-insulated cylinder and piston assembly (figure p3.1) contains an ideal gas at 10.13 bar and 294.3 k. a mechanical lock prevents the piston from moving. the length of the cylinder containing the gas is 0.305 m and the piston cross sectional area is 1.853 times 10^-2 m^2. the piston, which weighs 226 kg, is rightly fired and when allowed to move, there are indications that considerable friction is present. when the mechanical lock is released, the piston moves in the cylinder until it impacts and is engaged by another mechanical stop; at this point, the gas volume has just doubled. the heat capacity of the ideal gas is 20.93 j/mol k, independent of temperature and pressure. consider the heat capacity of the piston and cylinder walls to be negligible. (a) as an engineer, can you estimate the temperature and pressure of the gas after such an expansion? clearly state any assumptions. (b) repeat the calculations if the cylinder were rotated 90 degree and 180 degree before tripping the mechanical lock.
