A body at 50^(@) C cools in a surroundings maintained at 30^(@) C. The temperature at which the rate of cooling is half that of the begining is

A body is heated to a temperature of 75^(@)C and is allowed to cool. If the temperature of the surrounding is 35^(@)C , then the temperature at which the rate of cooling will be exactly half of that initially will be

A body cools from 50^@C to 40^@C in 5 mintues in surrounding temperature 20^@C . Find temperature of body in next 5 mintues.

A body cools from 50^@C to 40^@C in 5 mintues in surrounding temperature 20^@C . Find temperature of body in next 5 mintues.

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 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

As difference of temperature of body and surroundings increases, rate of cooling
