If an insoluble gas is passed through a volatile liquid placed in a perfectly insulated container, the temperature of the liquid will increase

A process is irreversible as long as Δ S for the system is greater than zero

The mechanical work done by a system is always equal to∫P.dV

Compression ratio of an Otto engine is comparatively higher than a diesel engine

Efficiency of an Otto engine is higher than that of a diesel engine for the same compression ratio

Otto engine efficiency decreases with the rise in compression ratio, due to decrease in work produced per quantity of heat

Diesel engine normally operates at lower compression ratio than an Otto engine for an equal output of work

Violates second law of thermodynamics

Involves transfer of heat from low temperature to high temperature

Both (A) and (B)

Neither (A) nor (B)

A refrigeration cycle violates the second law of thermodynamics

Refrigeration cycle is normally represented by a temperature vs. entropy plot

In a refrigerator, work required decreases as the temperature of the refrigerator and the temperature at which heat is rejected increases

One ton of refrigeration is equivalent to the rate of heat absorption equal to 3.53 kW
