A Journey through States of Water

Water in a pot boils and slowly reduces, until it dries up completely. Kabir says that water is gone forever. His grandmother says the water is still somewhere. Who is right?

Pointing at the white cloud rising from a kettle, Om says, "Look, that's steam." His sister says real steam is invisible — that white stuff is something else. Who is right?

An ice cube floats in a glass of water. Sanvi says ice floats because it is a lighter substance than water, the same way wood is a light substance and floats. Is that the right reason?

On a hot day, droplets form on the outside of a cold bottle taken from the fridge. Maanasi says water must have leaked out from inside the bottle. Her brother says that water came from the air, not from inside the bottle. Who is right?

Neeraj says water always boils at exactly 100°C, wherever you are — on the plains, on a mountain, anywhere. His sister, who has lived in a hilly area, says that is not true everywhere. Who is right?

A glass is full to the brim with water, with an ice cube floating in it. Siya says when the ice melts it will add more water and the glass will overflow. Her brother says the water level will stay the same. Who is right?
