A familiar example of the stickiness of water occurs when you drink water through a straw â a process thatâs very similar to the method plants use to pull water through their bodies. You apply suction at the top of the straw, and the water molecules move toward your mouth.
Types of refrigerants. Chlorofluorocarbons (CFCs) These are refrigerants that contain Chlorine, Fluorine and Carbon. They were developed in the 1930's and were used in a variety of industrial, commercial, household and automotive applications.
The chemical reaction for CFC is: CCl3F = CCl2F + Cl. Uses. Due to their chemical properties, CFCs became useful as coolants and propellants. More commonly known as freon for refrigeration, CFCs are used extensively in appliances as a safe method of refrigeration. The other main use for CFCs has been as a propellant for aerosol cans.
