zon 5:14 PM Example Problem: 2d Law of Thermodynamics Which of the following is nor allowed by the 2d law of thermodynamics? An engine that converts 150 J of heat into 20 J of work and exhausts 130 J of heat into its surroundings. A. B. A refrigerator with a coefficient of C. A refrigerator that does 50 J of work D. An engine with an efficiency (e) performance (K) greater than 1 for every 100 J of heat it removes greater than 1 Example Problem: Charges in a Conductor If you add some amount of positive charge to a solid conductor of any shape, where will the charges arrange themselves within the conductor? A. They will arrange themsclves evenly over the surface of the conductor B. They will all group at the center of the conductor C. They will tend to arrange themselves towards one side of the condactor D. They will evenly distribute themselves throughout the volume of the . Example Problem: path-dependent workening from sate 1 These paths give throe options for Which is the correct expression for the work done on the system along the path 142?Explanation / Answer
D)
second law says that an engine with efficiency greater than or equal to 1 is not possible.
A)
for a conductor , the charge resides evenly on the surface
A)
p2 (V2 - V1)
since work done = area under the line
