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 290 K and the substance cools from 370 K to 330 K in 10 min, when will the temperature be 295 K?

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?

According to Newton's law, rate of cooling is proportional to the difference between the temperature of the body and the temperature of the air. If the temperature of the air is 20^(@)C and body cools for 20 min from 100^(@)C to 60^(@)C then the time it will take for it temperature to drop to 30^(@) is

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.

A substance has nearly zero resistance at a temperature of 1 K What is such a substance called?
