Describe an imaginary process that satisfies the first
law but violates the second law of thermodynamics.
6-1C Water is not a fuel; thus the claim is false.
6-2C Transferring 5 kWh of heat to an electric resistance wire and producing 5 kWh of electricity.
6-3C An electric resistance heater which consumes 5 kWh of electricity and supplies 6 kWh of heat to a
room.
6-4C Transferring 5 kWh of heat to an electric resistance wire and producing 6 kWh of electricity.
6-5C No. Heat cannot flow from a low-temperature medium to a higher temperature medium.
6-6C A thermal-energy reservoir is a body that can supply or absorb finite quantities of heat isothermally.
Some examples are the oceans, the lakes, and the atmosphere.
6-7C Yes. Because the temperature of the oven remains constant no matter how much heat is transferred
to the potatoes.
6-8C The surrounding air in the room that houses the TV set.
