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 temperature T of a cooling object drops at a rate proportional to the difference T-S where S is constant temperature of surrounding medium if initially T= 150^(@) C find the temperature of the cooling object at any time t

A piece of copper and another of germanium are cooled from room temperature to 77 K. The resistance of

A body at a temperature of 50^0F is placed outdoors where the temperature is 100^0F . If the rate of change of the temperature of a body is proportional to the temperature difference between the body and its surrounding medium. If after 5 min the temperature of the body is 60^0F , find (a) how long it will take the body to reach a temperature of 75 ^0 F and (b) the temperature of the body after 20 min.

An ideal gas is maintained at constant pressure. If the temperature of an ideal gas increases from 100K to 1000K then the rms speed of the gas molecules

An ideal gas is maintained at constant pressure. If the temperature of an ideal gas increase from 100K to 1000K then the rms speed of the gas molecules:

The temperature of a steel rod is 330K. Its temperature in 0^@ C is
