Question:
If a body cools from a temperature of 62°C to 50°C in 10 minutes and to 42°C in the next 10 minutes, then the temperature of the surroundings is
If a body cools from a temperature of 62°C to 50°C in 10 minutes and to 42°C in the next 10 minutes, then the temperature of the surroundings is
Show Hint
Use Newton's Law of Cooling to solve problems involving temperature changes over time. The formula gives insight into the cooling process by comparing the body temperature with the surroundings.

- 12°C
- 26°C
- 36°C
- 21°C
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
According to Newton's Law of Cooling, the rate of change in temperature is proportional to the difference between the temperature of the body and that of the surroundings. Using this law, the temperature of the surroundings is found to be 26°C.
