Question

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 contact to one fourth it's original volume? options.
(a) yes, because 5 is one fourth of 20.
(b) No, because there is no gas inside the bottle.
(c) No, because Celsius is not an absolute temperature scale.

Answer 1

Answer:

c) No, because Celsius is not an absolute temperature scale

Explanation:

converting  5 oC to kelvin which is the absolute temperature scale gives = 273 + 5 = 278 K

and converting 20 oC to kelvin = 20 + 273 = 293 K

the ratio = 278 / 293 = 0.94 approx 1 not 4
