Specific Heat Capacity

Postby Kellina Tran 2I » Sat Jan 20, 2018 4:16 pm

On page 269 of the textbook, it says the units for specific heat capacity is J. degrees Celsius^-1. g^-1, or J. K^-1. g^-1. Does the K stand for Kelvin and if so, how is that equivalent to degrees Celsius?

Yes, K stands for Kelvin. The "steps" or the magnitude of degrees on the Kelvin and Celsius scale are equivalent so they can be used interchangeably in definitions like units.

Yes it does stand for Kelvin. It is equivalent to degrees Celsius because specific heat equations usually involve temperature change. The magnitude for temperature change is the same for Kelvin and Celsius; so both units are interchangeable for specific heat capacity problems depending on which temperature units you are given in the problem.

The K stands for Kelvin. Specific heat capacity is the energy needed to raise the temperature by 1 degree and since 1 degree of Celsius is the same as 1 degree of Kelvin, you can use it interchangeably.
