A sealed, frictionless piston contains 2.0mol of an ideal monatomic gas initially at 20.0∘C and a pressure of 1.00atm. The gas is compressed isobarically until its volume is reduced to one-half of its initial value.
(a) Compute the work done on the gas during the compression. Give your answer in joules with the correct sign.
(b) Determine the change in internal energy of the gas resulting from the compression.
(c) Using your results from parts (a) and (b), calculate the amount of thermal energy transferred during the compression and state clearly whether energy enters or leaves the gas as thermal energy.
(d) Explain qualitatively how the temperature of the gas after compression compares with its initial temperature, and relate your explanation to the numerical results obtained in parts (a)–(c).
