If the doors of a refrigerator are left open for few hours, then the room temperature will
Detailed Explanation:
A refrigerator operates on the Second Law of Thermodynamics: it removes heat from inside and releases it (plus compressor work energy) outside. With doors open, heat expelled into the room exceeds heat absorbed from the room, causing a net temperature increase.
The compressor converts electrical energy into heat, adding extra thermal energy to the room. The cooling effect is localized and temporary, while the heating effect is continuous and distributed.
Therefore, the room temperature will increase, making Option 2 the correct answer.
