Question

Two identical cups of cocoa are kept on a table . One has a metal spoon in it and the other doesn't. After 5 minutes, the water present in which of the cup will be cooler? Why?

Answer 1

The one with the spoon will be cooler. Metal can gain and lose heat quickly, so the spoon can take heat from the cocoa quickly and lose it to the atmosphere quickly.

Answer 2

Answer:

THE CUP WHICH HAS A METAL SPOON WILL BE COOLER BECAUSE METALS EASILY GAIN AND LOSE HEAT. SO THE SPOON TAKES HEAT FROM COCA CUP AND LOSE IT INTO ATMOSPHERE.
