Derive Newton's law of cooling to show that the rate of loss of heat from the body is proportional to the temperature difference between the body and its surroundings.

Assertion: According to Newton's law of cooling, the rate of loss of heat, -dQ//dt of the body is directly proportional to the difference of temperature. Reason :This law holds for all type of temperature differences.

Assertion: According to Newton's law of cooling, the rate of loss of heat, -dQ//dt of the body is directly proportional to the difference of temperature. Reason :This law holds for all type of temperature differences. a) If both assertion and reason are true and reason is the correct explanation of assertion. b) If both assertion and reason are true and reason is not the correct explanation of assertion. c) If assertion is true and reason is false. d) If both assertion and reason are false.

In Newton's law of cooling (d theta)/(dt)=-k(theta-theta_(0)) the constant k is proportional to .

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

Newton's law of cooling states that the rate of change of the temperature T of an object is proportional to the difference between T and the (constant) temperature tau of the surrounding medium, we can write it as (dT)/(dt) = -k(T - tau) k gt 0 constant An cup of coffee is served at 185^(@)F in a room where the temperature is 65^(@)F . 2 minutes later the temperature of the coffee has dropped to 155^(@)F . log_(e)3 = 1.09872, log_(e).(3)/(4) = 0.2877 Time required for coffee to have 105^(@)F temperature is
