First Law of Thermodynamics: A compression, at a constant pressure of 140 kPa, is performed on 4.0 moles of an ideal monatomic gas for which CV = 3/2 R. The compression reduces the volume of the gas from 0.26 m3 to 0.12 m3. What is the change in the internal (thermal) energy of the gas during this process? (R = 8.31 J/mol ? K)
A. -29 kJ
B. -49 kJ
C. 29 kJ
D. 49 kJ
E. 0 kJ
