If the equation is balanced: The coefficient numbers in the equation show the number of molecules, formula units, or atoms of the species involved in.
A cloud is made up of liquid water droplets. A cloud forms when air is heated by the sun. As it rises, it slowly cools it reaches the saturation point and water condenses, forming a cloud. As long as the cloud and the air that its made of is warmer than the outside air around it, it floats!
Quick Answer. Clouds form through the evaporation and condensation of water. As water molecules shift between vapor, liquid and solid, they move through the air. When a small amount of air cools very quickly and reaches saturation, the water can condense and become a cloud.
