is 40 degrees C concidered to be twice as high as 20 degrees C?

Question

why or why not?

Answer 1

this is difficult... is 40 two times greater than 20?

Answer 2

No.

0 C is not the zero point of heat. It's merely the freezing point of water.

0 Kelvin (or -273.15 C) is the zero point of heat. At this temperature, no heat is present. Nothing can be colder than this.

You could argue that 20 Kelvin is half as hot as 40 Kelvin, because 40 Kelvin is twice as far from absolute zero, the zero point of heat, but you cannot say this about Celsius or Fahrenheit temperatures.

Answer 3

Not really, because temperatures can go all the way down to absolute zero (the temperature at which everything is frozen, including hydrogen).

This temperature is -273.15 degrees C. So as you can see, a 20-degree difference is really less than a 10% temperature change.

Answer 4

No. The reason is because the Celsius temperature scale is NOT an absolute scale, that is, it has an arbitrary point for zero. If these temperatures are converted to Farenheit, for example, they are 68 and 104 degrees F, respectively.

Look up "absolute temperature scale" for more information.

Answer 5

Absolute Zero is way lower than 0C.

For aging of material using the Arhennius equation, aging could be more or less than twice as fast at 40C, depending on "activiation energy".

Answer 6

two answers, yes and no.

yes in a totally subjective way. (non-scientific)

no, really... temperature is a function of average kinetic energy and the difference betwee those two is like 10%.

If you want percentages, convert to the K scale, where 0K actually means 0 kinetic energy, so 10K would be half 20K etc

Answer 7

yes.
Since you are not converting celsius into anything you are using the same format and you can just double the numbers
