Question

"The rate of loss of heat $\frac{-dQ}{dt}$ of the body is directly proportional to the temperature difference $\Delta T=(T_2-T_1)$ of the body and surroundings". This statement is:

• A. Law of thermometry
• B. Newton's law of cooling
• C. Law of calorimetry
• D. Zeroth law

Answer 1

The correct option is B Newton's law of cooling

$\frac{-dQ}{dt}{T}_2=T_1$

is a theory of Newton's law of cooling
