Is it common knowledge that the temperature of air rises as it is compressed. An inventor thought about using this high-temperature air to heat buildings. He used a compressor driven by an electric motor. The inventor claims that the compressed hot-air system is 25 percent more efficient than a resistance heating system that provides an equivalent amount of heating. Is this claim valid, or is this just another perpetual-motion machine? Explain.

Respuesta :

Answer:

It is a perpetual motion machine.

Explanation:

The claim of an inventor is not valid because a device can not deliver more energy than it input or there is no device that can produce more energy than it input. Therefore,  the compressor cannot produce more energy as compared to another conventional heating system that runs by the e power input. However, the claim of inventor violates the rule or first law of thermodynamics and So, it is only a perpetual motion of first kind PMM1.
