Question

A Balloon has volume 10 l at the surface of water. Into what height should bring so that its volume increased to 25 l?​

Answer 1

Answer : The height of the water should be, 15 L

Explanation :

We are given,

The volume of balloon at surface of water = 10 L

Increased volume of water = 25 L

The increased height of the water = Increased volume of water - volume at the surface of water

Now, putting all the given values in above expression, we get

The height of the water = 25 L - 10 L = 15 L

Therefore, the height of the water should be, 15 L
