### Heat Capacity of Water

The heat capacity of water is 4.184 J • C^-1 g^-1 or 4.184 J • K^-1 g^-1. Why is the heat capacity of water per celsius and per Kelvin the same? I thought that the conversion rate between Celsius and Kelvin is +273 K.

A unit change in kelvin is the same change in Celsius. The equation states per kelvin/Celsius so if one unit of kelvin changes so does 1 unit of Celsius.

yea basically if Celsius is changed by 1 decree then so is Kelvin since its just addition

### Re: Heat Capacity of Water

the unit change is all the same no matter whether in Celsius or Kelvin in this case

Just because the values would be different, does not mean the rate will be. The rate is constant and can be applied to both Celsius and Kelvin since they are "proportional"

It would be proportional so the change would essentially be the same.

### Re: Heat Capacity of Water

Heat capacity is calculated using the equation $C=\binom{E}{\Delta T}$
where "C" is the Heat Capacity, "E" is the energy added per gram of substance, and "ΔT" is the change in temperature.

Since the energy added is in the same unit (J), the mass of water heated is the same unit (g) and heat necessary to cause an increase in 1.0oC and 1.0K are the same, then so are the representations of heat capacity shown.
