A Cylinder Containing an Ideal Gas Has a Volume of 2

Multiple Choice

A cylinder containing an ideal gas has a volume of 2 m³ and a pressure of 1.6 × 10⁵ Pa at a temperature of 320 K.The cylinder is placed against a metal block that is maintained at 840 K and the gas expands as the pressure remains constant until the temperature of the gas reaches 840 K.The change in internal energy of the gas is 6.7 × 10⁵ J.Find the change in entropy of the block associated with the heat transfer to the gas.
