Answer:

4186 Joules

Step-by-step explanation:

The specific heat capacity of a substance is defined as the amount of heat needed to raise the temperature of 1 kg of the substance by 1 Kelvin. In formula,


C_s = (Q)/(m \Delta T)

where

Q is the amiunt of heat needed

m = 1 kg is the mass


\Delta T = 1 K

is the variation of temperature of the substance

For water, the specific heat capacity is
4186 J/(kg K). This means that the heat energy required to raise 1 kg of water by 1 K is exactly 4186 J.
