2.WHO INVENTED THE REFRIGERATOR?
Refrigeration is the process of making and keeping things cold. The way to make things cold is to remove heat from them. So refrigeration is any process that removes heat to make cold.
In ancient times, of course, snow and ice were the natural way to refrigerate things. Wines were cooled in this way. But even in ancient times another way to produce cold was known.
1.HOW DID SUPERSTITIONS BEGIN?
It is very hard to define “SUPERSTITION” to a layman or a kid. If you define it as belief in something, it is not so. There are many things all of us believe in that cannot be proved. At certain times in man’s history, everyone believed in certain things that we now consider as Superstitions. And the people who believed in them at that time were not Superstitious at all!
