    Answer: temperature of the hot reservoir is 303.52K

    Explanation:

    Th=temperagture of hot reservoir

    Tc=temperature of cold reservoir 263K

    Eff=efficiency of the refrigerator

    Cop=coefficient of performance

    7

    Eff=1/cop

    Eff=1/7

    Eff=0.142

    Eff=1-263/th

    0.142-1=-263/th

    -0.858=-263/th

    Th=303.52K
