Question

In a day, an electrical resistance heater uses 10 kW-h of electricity. In the same day, the heater delivers 9 kW-h of heat to the house in which it is located. Is this possible or is this a perpetual motion machine? If so, what kind? Explain your reasoning.

Answer 1

Step-by-step explanation:

Heat absorb, Q = 10 kWh

Work, W = 9 kWh

As by 1 st law of inventor

Q = W

But here, Q ≠ W , so the machine is perpetual motion machine of 1 st kind.
