Write the value of the specific heat capacity of water with its unit.

(N/A) The specific heat capacity of water is the amount of heat required to raise the temperature of $1 \ kg$ of water by $1 \ K$ (or $1 \ ^\circ C$).
The value of the specific heat capacity of water is approximately $4186 \ J \ kg^{-1} \ K^{-1}$ or $4.186 \ J \ g^{-1} \ ^\circ C^{-1}$.
In terms of calories,it is $1 \ cal \ g^{-1} \ ^\circ C^{-1}$.
