Question

A boy was sucking cold drink from the bottle with the help of a straw.Then he made it airtight by putting plasticine around the straw on the mouth of the bottle. Will he be able to suck the cold drink any more ? Why ?

Answer 1

no he can't bcz there is no space for the cool drink to travel.....so he can't drink

Answer 2

no because when the bottl is airtight no air can enter the bottle and atmospheric pressure will be less in the bottle and cold drink will not rise into the straw ./
