Why does it not matter if kelvin or celsius is used in specific heat capacity?

Question

I understood it before, but I completely forgot it and I need to know it now. Any help is appreciated.

Answer 1

A degree of celcius and one kelvin are the same amount.

1degree celcius = 1 kelvin.

In specific heat, it is the amount of energy required to raise the temperature one degree. It will not matter if you have celcius or kelvin in there because it will have the same effect. If you raise the temperature one degree celcius or if you raise it one kelvin, you have raised it the same amount of temperature.

Now, a reading in celcius is not the same reading in kelvin, but the increments in the temperature scales are the same.

Answer 2

The specific heat capacity is the amount of energy required to raise the temperature of a given amount of a substance by one degree (normally 1 gram of a substance by one degree).

The kelvin and celcius scales are the same (ie 1K = 1C), the only difference is that the kelvin scale starts at approx -273C (absolute zero) whereas the celcius scale starts at 0C, the freezing point of water.
