Homework Statement
Three moles of an ideal monoatomic gas trebles its initial volume in an isobaric expansion from state A to state B. The gas is then cooled isochorically to state C and finally compressed isothermally until it returns to state A. The molar gas constant is R = 8.314 J mol–1 K–1 and Boltzmann's constant is 1.38 × 10–23 J K–1.
(a) If state B corresponds to a pressure P = 5 atm (1 atm = 1.013 × 10^5 Pa) and temperature T = 535 °C, determine the temperature of the gas in state A.
