Answer:
4186 Joules
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,
[tex]C_s = \frac{Q}{m \Delta T}[/tex]
where
Q is the amiunt of heat needed
m = 1 kg is the mass
[tex]\Delta T = 1 K[/tex]
is the variation of temperature of the substance
For water, the specific heat capacity is [tex]4186 J/(kg K)[/tex]. This means that the heat energy required to raise 1 kg of water by 1 K is exactly 4186 J.
