Newton's law of cooling is used to determine

The correct answer is option 2) i.e. Temperature of an object after a given time

CONCEPT:

• Newton's law of cooling: Newton's law of cooling states that the rate of loss of heat from a body is directly proportional to the difference in the temperature of the body and its surroundings.
• It is given by the equation:

\(⇒ \frac{dT}{dt} = k(T_t -T_s)\)

Where k is the cooling constant, Tt is the temperature at time t, Ts is the temperature of the surrounding.

• The temperature at time t, 

⇒ Tt  = Ts + (T0 – Ts) e-kt

EXPLANATION:

• The statement of Newton's law of cooling is not applicable to the mass, volume, and pressure of a body that loses heat.
• The equation derived from Newton's law of cooling is used to determine the temperature of an object after a given time when it loses heat to the surroundings.
