question 69

Multiple Choice

A sealed rigitd tank contains 30 moles of an ideal gas, at an initial temperature of $270 \mathrm {~K}$ The pressure of the gas is increased until the final pressure equals 1.40 times the initial pressure. The heat capacity at constant pressure of the gas is $32.0 \mathrm {~J} / \mathrm { mol } \cdot \mathrm { K }$ What is the change in the internal (thermal) energy of the gas during this process? (R = 8.31 J/mol ∙ K)

• A) 77 kJ
• B) 100 kJ
• C) 130 kJ
• D) -50 kJ
• E) -23 kJ
