question 70

Multiple Choice

A cylinder containing an ideal gas has a volume of 2.0 m³ and a pressure of 1.0 ´ 10⁵ Pa at a temperature of 300 K.The cylinder is placed against a metal block that is maintained at 900 K and the gas expands as the pressure remains constant until the temperature of the gas reaches 900 K.The change in internal energy of the gas is 6.0 ´ 10⁵ J.Find the change in entropy of the block associated with the heat transfer to the gas.

• A)0
• B)+670 J/K
• C)-440 J/K
• D)-1 100 J/K
