question 212

Multiple Choice

The temperature of an ideal gas in a sealed rigid 0.60- $m ^ { 3 }$ container is reduced from 460 K to $270 \mathrm {~K}$ The final pressure of the gas is $90 \mathrm { kPA } .$ The molar heat capacity at constant volume of the gas is 28.0 J/mol ∙ K. How much heat is absorbed by the gas during this process? (R = 8.31 J/mol ∙ K)

• A) -130 kJ
• B) -170 kJ
• C) 130 kJ
• D) 170 kJ
• E) 0 kJ
