Question

Take some water in a container and seal it. Place it on a heater. The water starts boiling and changes into vapour. Now allow the container to cool down for some time and then open the seal. What will happen to the amount of water?


  1. Will be more than the initial amount

  2. Will be less than the initial amount

  3. Will be equal to the initial amount

  4. Can’t be said


Solution

The correct option is C

Will be equal to the initial amount


The water does not escape from the container (the container is sealed), it only gets converted into vapour and then back into liquid form when cooled. So the amount of water will be equal to the initial amount.
