Why is it called h2o?
The scientific name for water is H2O.
It is called H2O because it has two atoms of hydrogen (H) and one atom of oxygen (O).
When water boils, water molecules move very fast.
Water molecules move so fast that they actually break apart from each other and escape into the air as water vapor or steam..
