Answer» If the door of the refrigerator is kept open in a room, it warms up the room. Explanation:- Running the refrigerator makes the room warmer and if you leave the door open, the room warms up even faster. The first rush of cold air may cool things down a little, but in the long run, the room will get warmer. To see why, we need to think of heat as energy and cold as a lack of energ.But the refrigerator can’t actually produce cold. All the refrigerator does is move heat, or energy, from one place to another. As the food inside the refrigerator loses its heat–or, in other words, gets colder–thatheat ends up in the room. 1 st one is correct answer |
