Keep cool yourself with Refrigerator!

Being in the tropical region the 'ice' has been a wonder matter since my childhood. Then I tasted the sweetness and the coldness of the 'ice fruit' purchased from cart man . We used to peep into the ice factory with much enthusiasm how this wonder is being made. Then came the 'ice-making chest' in the medical shops. I had placed the water inside the ice tray of its freezer compartment and later opened the freezer with amazement to see the water frozen into ice cubes. This 'ice chest' was nothing but our Refrigerator! It works on the principle of compressed gas on being released out, produces coolness at the site of its release. At school we were explained this with an example: 'while releasing the air from the bicycle tube by taking out the tube valve, place your finger tip on the mouth of the air releasing tube. You shall now feel the coolness!' Yet another example was also given: 'a drop of spirit put on the skin produces coolness by its evaporation into the air!' Similarly, inside the refrigerator (fridge) a gas like Hydrochlorofluorocarbon (HCFC) is used. It is first compressed to its liquid state and then released into in its gaseous state, when it cools down our food kept in the fridge, taking out the heat from them!

Every place we go, we see this fridge being used. It preserves food preventing wastage by decay and enables us to store our food purchased in bulk quantity. It also gives us cool drinks that are inevitably preferred in summer to keep ourselves cool. Can we now imagine a life without this wonderful refrigerator?!
