The rate of cooling of a substance in moving air is proportional to the difference of temperatures of the substance and the air. A substance cools from 36 degree celsius to 34 degree celsius in 15 minutes. Find when the substance will have the temperature 32 degree celsius , it being known that the constant temperature of air is 30 degree celsius.

The rate at which a substance cools in moving air is proportional to the difference between the temperatures of the substance and that of the air.If the temperature of the air is 290K and the substance cools from 370K to 330K in 10min, when will the temperature be 295K?

The velocity of sound in a gas is directly proportional to the square root of the temperature of the gas taken in degree celsius .

A particular substance is being cooled by a stream of cold air (temperature of the air is constant and is 5^(@)C ) where rate of cooling is directly proportional to square of difference of temperature of the substance and the air. If the substance is cooled from 40^(@)C to 30^(@)C in 15 min and temperature after 1 hour is T^(@)C, then find the value of [T]//2, where [.] represents the greatest integer function.
