Answer:
Step-by-step explanation:
Freon, which is a type of refrigerant, has a special property that makes it useful for cooling. It has a low boiling point, meaning it can easily turn from a liquid into a gas at low temperatures. This process helps absorb heat from the surroundings and cools the desired area. Freon also has a moderate critical temperature, which allows it to work well in different conditions. However, it's important to note that some types of Freon have been phased out due to their harmful effects on the ozone layer. Safer alternatives are now used instead.
