A body cools in 7 minutes from `60^(@)C` to `40^(@)C`. What will be its temperature after the next 7 minutes? The temperature of the surrounding is `10^(@)C`. Assume that Newton's law of cooling holds good throughout the process.

Explanation

To solve the problem using Newton's Law of Cooling, we will follow these steps:

### Step 1: Understand the given data
- Initial temperature of the body, \( T_1 = 60^\circ C \)
- Final temperature after 7 minutes, \( T_2 = 40^\circ C \)
- Surrounding temperature, \( T_0 = 10^\circ C \)
- Time interval, \( t = 7 \) minutes = \( 7 \times 60 = 420 \) seconds
