If the temperature of a water bath is 1040 F then its value in degree Celsius scale will be?
A body cools down from 500C to 450C in 5 minutes and to 400C in another 8 minutes. Find the temperature of the surrounding.
A calorimeter contains 50 g of water at 50^0 C. The temperature falls to 450 C in 10 minutes. When the calorimeter contains 100 g of water at 500 C, it takes 18 minutes for the temperature to become 450 C. Find the water equivalent of the calorimeter.
