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.
Today's Refrigerators. Modern refrigerators don't use CFC because CFCs are harmful to the atmosphere if released. Instead they use another type of gas called HFC-134a, also called tetrafluoroethane. HFC turns into a liquid when it is cooled to -15.9 degrees Fahrenheit (-26.6 degrees Celsius).hen you pass the compressed gas through the coils on the back or bottom of a modern refrigerator, the warmer gas can lose its heat to the air in the room. Remember the law of thermodynamics. As it cools, the HFC can change into a liquid because it is under a high pressure.
