question 83

Multiple Choice

A sealed rigid tank contains 29 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 1.90 times the initial pressure. The heat capacity at constant pressure of the gas is $24.0 \mathrm {~J} / \mathrm { mol } \cdot \mathrm { K }$ How much heat is absorbed by the gas during this process? (R = 8.31 J/mol ∙ K)

• A) 110 kJ
• B) 170 kJ
• C) 230 kJ
• D) -52 kJ
• E) 7.0 kJ
