Answer the following true or false. Explain.

(a) The maximum thermal efficiency of any power cycle operating between hot and cold thermal reservoirs at 10008C and 5008C, respectively, is 50%.

(d) A product website claims that a heat pump capable of maintaining a dwelling at 708F on a day when the outside temperature is 328F has a coefficient of performance of 3.5. Still, such a claim is not in accord the second law of thermodynamics.

(e) There are no irreversibilities within a system undergoing an internally reversible process.
