The reason of faster cooling when hot coffee pours into a saucer
Answer to Problem 31A
The saucer has more surface area of evaporation & air movement during pouring.
Explanation of Solution
The evaporation is depending on surface area .
More the surface area more will the evaporation .
As we pour the hot coffee into the saucer due to movement of liquid it evaporates.
Conclusion:
The saucer has more surface area of evaporation & air movement during pouring.
