Question

according to the second law of thermodynamics, which of thefallowing applies to the heat received from a high temperaturereservoir be aheat engine operating in a complete cycle? a must be completely converted to work b equals the entropy increase c converted completely into internal energy d cannot be completely converted to work according to the second law of thermodynamics, which of thefallowing applies to the heat received from a high temperaturereservoir be aheat engine operating in a complete cycle? a must be completely converted to work b equals the entropy increase c converted completely into internal energy d cannot be completely converted to work

Explanation / Answer

   cannot be completely converted to work    dQ   =   dU   +   dW    According to second law, no engine canconvert all supplied heat into work done only.
