The temperature of a cold drink in a warm room rises with time as a result of heat transfer. Is this a reversible process?Question 1Select one:a.Yesb.No

Select the most accurate response. An externally reversible process is one thatQuestion 4Select one:a.has no heat transfer, dQ=0b.does no work, dW=0c.occurs at constant volume, dV=0d.exchanges heat dQ with its surroundings only through an infinitesimal temperature difference dTe.exchanges an infinitesimal amount of heat dQ with the surroundings, which must be colder than the contents of the systemf.A and B

How does heat transfer occur?Question 4Select one:a.from cold to hot until the hot object becomes coldb.from hot to cold until both objects reach the same temperaturec.from cold to hot until both objects reach the same temperatured.from hot to cold until the cold object becomes hot

On its own, heat flows from hot objects to cold objects.Group of answer choicesTrueFalse

The ideal vapour-compression refrigeration cycle is not a reversible cycle becauseQuestion 1Select one or more:a.heat input is not isothermal across an infinitesimal temperature differenceb.the ideal compression process is non-isentropicc.heat rejection is not isothermal across an infinitesimal temperature differenced.expansion process through the throttling valve is irreversiblee.phase changes that occurring during heat input and output cannot be reversed
