Chapter 1: 1.4. (page 5)

Does it ever make sense to say that one object is "twice as hot" as another? Does it matter whether one is referring to Celsius or Kelvin temperatures? Explain.

No, the statement according to physics is wrong. And the Celsius and Kelvin scales cannot give a good comparison of temperatures..

Step by step solution

differences between heat and temperature.

There are two distinct terms- "heat" and "temperature". heat is a term for transfer of energy from one point to another from higher temperature to the lower temperature; whereas temperature is the measure of degree of hotness or coldness of the object.

Comparison of heat and reading it in terms of temperature

Hence one can say that object has twice the temperature than the other, since the quantities has a clear description on how they are measured

The values of absolute zero of Celsius and Fahrenheit scales.

If one object was 40⁰C and another 80⁰C then in Celsius scale one is twice the other. But if we convert into Fahrenheit scales those temperatures come to 313.15K and 353.15K. So in this respect we can say that second object is not twice the temperature of the first. Hence we can explain the contradiction that these scales cannot be measured in the same segment.
