Question

Does It Everton make Sense to say that one object is twice as hot as another?
Does It matter whether one is referring to Celsius or Kevin temperatures? explain.

Answer 1

1. Yes we can always say that one object is twice as hot as the other, for this is like saying that one object's length is twice as the other execpt that here we are referring to temperatures instead of length.

2 Yes the unit does matter here. Again consider the example of object's length where you can write length in metres or in kilometres and both will share the same relation of being twice of the other however for the case of temperature we know that K = C +273.15 and so if you mean twice in celsius will not imply twice in Kelvin and vice versa. But Kelvin being the SI unit and also never being negative is a natural choice for comparing temperatures. Besides in celsius scale we have -1 and 1 then you can't even compare them by the relation of positive multipes. So it is advisable not to use celsius for comparing temperatures.
