Do you think it's possible for water to be boiling but not hot?
Actually it is! In this episode of BYJU’s Now We Know, we explore what exactly boiling is. We tend to associate boiling with heating, but heat is only a way of getting water to boil. We can boil water without heat too!

The clue to this lies in the mountains and their low atmospheric pressure. Is the boiling point of water always 100 degree celsius? What does it mean for the boiling point to increase or decrease?
Watch this video where we explore the concepts of vapour pressure and atmospheric pressure. Finally, we show you an experiment where water is boiling without any heat at all!
What’s more?! We will also give you a do-it-yourself method of boiling water without any heat.
You would essentially be replicating some parts of what happens to water in space.
