Rajesh took two identical glasses containing the same amount of hot milk at the same temperature He kept one glass undisturbed .While the other one he continously stirred using a spoon .Then among them milk in which glass cools faster ? Why? |
| Answer» Solution :The milk in GLASS which is stirred by a SPOON COOLS first because when we stir using a spoon it will increase the movement of molecules the cold molecules on the SURFACE will settle at the bottom and hot molecules form bottom reach the top .Thus stirrring increase the HEAT transfer rate by convection | |
