Question

According to Newton's law of cooling, the rate of cooling is proportional to ${\left(\Delta \theta \right)}^n$, where $\Delta \theta$ is the temperature difference between the body and the surroundings and $n$ is equal to

• A. Three
• B. Two
• C. One
• D. Four

Answer 1

The correct option is C One

According to Newton's law of cooling, as the rate of cooling is directly proportional to temperature difference between the body and the surroundings
i.e., −dθdt∝Δθ⇒n=1
