The temperature of the body reduces by 0.5 °C in 1 min.
So the temperature of the body reduces by 1°C in 1/0.5 min = 2 min
Therefore the temperature of the body reduces by 25°C in 2×25 °C = 50 °C
The rate of cooling of a body is directly proportional to the difference in temperatures of the body and the surrounding, provided difference in temperature should not exceed by 30°C.
