When it is covered by a damp cloth, Water gains K.E and so can over come the forces of attraction, causing it to evaporate, and evaporation has a cooling effect (You Should Know This) thus keeping the Milk inside cool for a further period of time


Hope It Helps, If It Does, Don't Forget +REP

oh i wrote that water have k.e and transfer it to other molecules and thus transfer the k.e to the milk bottle by convection

omg!!! they repeated 3 question now in this exam this question and the pressure question and the truck question hey which mcq was this question repeated the milk one

[idk]

hey guys i wrote that the milk molecules cant evaporate as damp cloth is there and that the milk will transfer its heat energy to water and water evaporates instead of milk and thus milk stays cool.is this right?

Hey everyone,

It was a little bit similar to the thermos flask right?

[thukon]

I got it wrong. I wrote that water evaporates from the dish. lol. I thought the cloth was to stop the milk from evaporating.
Will I get ANY marks for that??
