HOW IS WATER FORMED?

Water is a second product of flame. Steam is the first form of water in every flame of every lamp and every flaming lira, but when the heat is subtracted from it it shrinks and condenses into water. Ice and snow are solid forms of waterwater is its fluid form, steam is its vaporous or cloud form. Oxygen and hydrogen are the gaseous form of the fluid wei call water. If you add beat to ice and snow they change into a fluid. Add heat to the fluid, it change!" into vapor (nearly as large as the gases out of which it is formed. Gases 1987, vapor 1600).. Add heat to the vapor or steam, it is decomposed ; into two simple elementary gases, hydrogen and oxygen. Water h found in a state of .nature, as. snow, and ice,.water and vapor. Oxygen (S-9ths of * water) is l>sth visible (cloudg)" and' Jiufftiible.
