An object cools from to in minutes, when the surrounding temperature is . Then the time taken by the object to cool from to is
[Take ]
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
According to Newton's cooling law, rate of cooling is dθdt∝θ-θ0 Here, θ=the temperature of the body θ0=Room temperature(constant) Let k be the proportionality constant and θ be the temperature. Therefore,…
