Answer:
784500 Joules
Explanation:
To start, you will need an equation to find the change in energy. This can be found by using [tex]Q = mCT[/tex] or by using integrated heat capacities.
to find the mass of water,
[tex]2.5L * 1kg/L = 2.5 kg water[/tex]
1kg/L is the density of water.
Then, [tex]Q = 2.5kg*4.184J/gC*(100-25)[/tex]
Notice that all of the units do not cancel out properly, so some unit conversions are needed to find the correct answer.
