Refrigerators are usually kept at about 5∘c, while room temperature is about 20∘c. if you were to take an "empty" sealed 2-liter soda bottle at room temperature and place it in the fridge, would you expect it to contract to one-fourth its original volume? 1. yes, because 5 is one-fourth of 20. 2. no, because there is no gas inside the bottle. 3. no, because celsius is not an absolute temperature scale.
