Answer Posted / rahul patole
A basic law of physics called the conservation of energy
says you can't make or destroy energy: if you have some
energy you don't want (such as heat in your kitchen), you
can't get rid of it completely. All you can do is change it
into another form or move it to another place. If you open
your refrigerator door in the hope that you'll cool the
kitchen, all the heat that gets sucked in has to go
somewhere else. The only place it can go is out of the back
of the machine. You may have noticed that the grid of fins
on the back of a refrigerator gets pretty hot—and that's
why: they're giving off all the heat that would normally be
inside. You can find out more in our article on how
refrigerators work.
