# What is the specific heat of water with three units that include calories?

Jul 22, 2017

Depends on what you mean by three units... at ${25}^{\circ} \text{C}$ and $\text{1 atm}$... and constant atmospheric pressure...

${C}_{P} = \text{1.000 cal/g" cdot "K}$

or

${C}_{P} = \text{1.000 cal/g"^@ "C}$

or if we went further, we could convert to the molar specific heat capacity...

${C}_{P} = \text{1.000 cal/"cancel"g" cdot "K" xx (18.015 cancel("g"))/"1 mol}$

$= \underline{\text{18.015 cal/mol"cdot"K}}$

or

${C}_{P} = \underline{\text{18.015 cal/mol"^@ "C}}$
