A cylinder containing an ideal gas has a volume of 3.0 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 9.0 * 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) "-1700 J/K"
D) "-1100 J/K"
