A hot body is placed in cold surroundings It's rate of cooling is `3^(@)C` per minute when its temperature is `70^(@)C` and `1.5^(@)C` per minute when its temperature `50^(@)C` it s rate of cooling when its temperature is `40^(@)C` .

A hot body is kept in cooler surroundings. Its rate of cooling is 3^(@)C /min when its temperature is 60^(@)C and 1.5^(@)C / min when its temperature is 45^(@)C . Determine the temperature of the surroundings and the rate of cooling when the temperature of the body is 40^(@)C

A body cools at the rate of 4^@C per minute when its temperature is 70^@C . What will be its rate of cooling when its temperature is 50^@C ? (Assume temperature of surrounding to be 30^@C )

A body cools at the rate of 3^(@)C// min when its temperature is 50^(@)C . If the temperature of surroundings is 25^(@)C then the rate of cooling of the body at 40^(@)C is

A hot body is placed in cooler surroundings. When the body temperature is 75^(@)C , the rate of cooling is 4^(@)C//min . When it is 55^(@)C , the rate of cooling is 2^(@)C//min . The temperature of the surroundings is

A metal sphere cools at the rate of 1.6^@C/min when its temperature is 70^@C . At what rate will it cool when it's temperature is 40^@C . The temperature of the surrounding is 30^@C .

A metal sphere cools at the rate of 0.05^@ C/s when its temperature is 70^@ C and at the rate of 0.025^@ C /s when its temperature is 50^@ C . Determine the temperature of the surroundings and find the rate of cooling when the temperature of the metal sphere is 40^@C .
