Temperature dependency is responsible for the process that hot water freeze faster than cold water.
The effect given above is called Mpemba Effect. According to this idea hot water freezes more quickly as compared to cold water. But until now there is no convincing explanation for this strange phenomenon. One idea is that hot containers make better thermal contact with a refrigerator and so conduct heat more efficiently because a good conductor is good fro the transfer of heat. Another idea about this effect is that warm water evaporates more quickly and since this is an endothermic process, it cools the water making it freeze more quickly.
warm water evaporates rapidly and since this is an endothermic process, it cools the water making it freeze more quickly.
(2) distillation (4) sublimation
Answer:
(3) esterification
Explanation:
1) Deposition is a process in which a vapor directly condenses into a solid. It is the reverse of sublimation and therefore a process which involves a physical/phase change.
2) Distillation is a process in which a liquid mixture is separated based on the differences in their boiling points. This is a physical separation and not any form of a chemical change.
3)Esterification is an organic reaction in which a carboxylic acid is treated with an alcohol to form an ester.
4) Sublimation is again a physical/phase change process in which a solid gets converted into a gas.
