In the above circuit, the voltage across the resistor
is
If the voltage
is suddenly increased to
what has happened to the entropy of the system of electrons in the circuit?
If a warm object contacts a cold object, in which direction will the heat flow?
air particles are flying around a room. Suddenly, all the particles are moved to one side of the room. What has happened to the entropy of the system?
If we put a cup of water into a freezer, what will happen to its entropy?
If ice cream is melted in a warm room, what happens to the entropy of the system?
