Question

I will mark brainlist for the best answer **There is closed room with Open fridge why does the room temperature increase instead of decrease?** 50 Points !!!​

Answer 1

Answer :

A fridge can be though of as a "heat pump". It takes air inside the fridge and cools it by removing heat from it. This heat has to go somewhere, though, and is usually blown out the back of the fridge by a little fan. (If you feel the back of a fridge on the outside it will usually be warm if the unit is running. This is why the temperature decreases.

Explanation:

Answer 2

There is closed room with open fridge open fridge the room temprature is increase instead of Decrease because according to second law of thermodynamics there would be conversion of heat takes place from electrical energy .

And the heat realised by the fridge is given to the surrounding there is two source of heat let us see in below

Heat of surrounding inside fridge -----------given ------- surrounding inside room ------------room is closed -------so the temprature must be of room temprature but increment is due to

-----------the heat produced by motor in which electrical energy get converted to heat energy

In closed room

initial

Room temperature + fridge temprature

Final

Room temprature + fridge temprature + heat produced due to conversion of electrical energy by motor .

so the room temprature increase
