Concept Series 2

An air conditioning unit is supplied with power, and it cools an entire house without generating any heat. Which law of thermodynamics is violated? Explain why.

A substance is thermally insulated, so that no heat can be exchanged with the surroundings. Is it possible for the temperature of the substance to change? Explain why.

How much work is required to move a charge from on location on an equipotential to another point on the same equipotential? explain.

You're working with a circuit that contains a capacitor. After allowing current to flow through circuit and charge up capacity, you disconnect the battery and unplug the capacitors from the circuit. As you remove the capacity, you receive a mild electric shock (even though it was unplugged!) Explain why.

Explanation / Answer

2nd law of thermodynamics is violated because it is impossible to have net heat flow.

Yes temperature can be change by doing work on the system.

Zero work is required because no change in potential energy.

Because of charged capacitor.
