A refrigerator transfers heat from the cold coling coils to the warm surroundings. Is it against the second law of thermodynamics? Justify your answer?

The second law of thermodynamics deals with transfer of

Is the function of refrigerator against the second law of thermodynamics? Explain.

Is the function of a refrigerator against the second law of thermodynamics? Explain.

Refrigerator transfers heat from a cold body(from inside) to hot body(outside atmosphere).Does it violate second law of thermodynamies?

Which limitation of heat engine put by the second law of thermodynamics ?

Asssertion: It is not possible for a system, unaided by an external agency to transfer heat from a body at lower temp. to another at a higher temp. Reason: It is not possible to violate the second law of thermodynamics.

An ideal refrigerator is used to transfer heat from a freezer at -23^@C to the surrounding at 27^@C . Its coefficient of performance is

If an ideal gas expands adiabatically will its temperature increase or decrease? Use first law of thermodynamics to justify your answer.
