A cylinder contains 10 moles of an ideal gas at a temperature of 300 K. The gas is compressed at constant pressure until the final volume equals 0.77 times the initial volume
The molar heat capacity at constant volume of the gas is 24.0 J/mol ? K and R = 8.31 J/mol ? K . How much heat is absorbed by the gas during this process? (R = 8.31 J/mol ? K) A) -22 kJ B) -17 kJ C) 22 kJ D) 17 kJ E) -5.7 kJ
