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.
