A 0.357 mol sample of N, (g), initially at 298 K and 1.00 atm, is held at constant pressure while enough heat is applied to raise the temperature of the gas by 12.3 K. Calculate the amount of heat q required to bring about this temperature change, and find the corresponding total change in the internal energy AU of the gas. Assume that the constant-pressure molar specific heat for N, (g), which consists of linear molecules, is equal to 7R/2, where R = 8.3145 J/(mol-K) is the ideal gas constant.

Transcribed Image Text:A 0.357 mol sample of N, (g), initially at 298 K and 1.00 atm, is held at constant pressure while enough heat is applied to
raise the temperature of the gas by 12.3 K. Calculate the amount of heat q required to bring about this temperature change,
and find the corresponding total change in the internal energy AU of the gas.
Assume that the constant-pressure molar specific heat for N, (g), which consists of linear molecules, is equal to 7R/2, where
R = 8.3145 J/(mol-K) is the ideal gas constant.
