According to the Newton's law of cooling, the rate of cooling or rate of loss of heat is directly proportional to- Correct Answer All of the above

CONCEPT:

  • Newton's Law of Cooling: It states that the rate of cooling or rate of loss of heat is directly proportional to the temperature of the body, temperature of the surrounding medium, Nature, and extent of the exposed surface.


EXPLANATION: 

  • Newton's law of cooling states that rate of cooling or rate of loss of heat is directly proportional to-
    • The temperature of the body.
    • The temperature of the surrounding medium.
    • Nature, and extent of the exposed surface.

 

  • When we put hot water bucket cools fastly until it gets lukewarm, it stays so for a longer time.
  • This application is based on Newton's Law of Cooling.
