AIIMS 2018 Physics Refrigeration Cycles MCQ Question

The equation derived from the efficiency of a refrigerator, β = Q₂/(Q₂ - Q₁), leads to the expression Q₁ = Q₂(β - 1)/β, which accurately represents the relationship between the heat absorbed (Q₂) and the heat rejected (Q₁) in a refrigeration cycle. This demonstrates how the cooling effect (Q₂) and work input relate to the efficiency of the refrigerator. Since the other options are labeled as N/A, they do not provide any relevant information or alternative answers, making option A the only valid choice in this context. Understanding this relationship is crucial for analyzing the performance of refrigeration systems in thermodynamics.
