A container holds 4.5 mol of an ideal monatomic gas with a pressure of 124 kPa. The container initially has a volume of 0.17 m3.
(a) What is the temperature of the gas?
K
(b) What is the thermal energy of the gas?
J
(c) The gas undergoes an adiabatic expansion until it reaches a volume of 0.37 m3 and a pressure of 33.9 kPa. What is the thermal energy of the gas after the expansion?
J
(d) What is the temperature of the gas after the expansion?
K
(e) How much energy went into or out of the gas as work during the expansion? (Positive for energy into the gas, negative for energy out of the gas.)
J
(e) How much energy went into or out of the gas as heat during the expansion? (Positive for energy into the gas, negative for energy out of the gas.)
J
