P213 FINALFALL 2004Form A1. One mole of an ideal gas expands slowly and isothermally at temperature T until its volume isdoubled. The change of entropy per molecule of this gas for this process is:A. ln(2) / TB. 2 kC. zeroD. k ln(2)E. k T ln(2)2. The heat capacity of object B is twice that of object A. Initially A is at 300K and B is at 450K.They are placed in thermal contact and the combination is isolated. The final temperature of bothobjects is:3. A 10 g ice cube at -10°C is placed in a lake whose temperature is 15°C. Calculate the change inentropy of the ice cube as it becomes water and reaches the lake temperature.A. 15.2 J/KB. 3.8 J/KC. 3.1 J/KD. 2.0 J/KE. 0.8 J/KPage 1
