How many kilojoules of heat are needed to raise the temperature of 10.00 KG of liquid water from 24.6 degrees celsius to 46.2 degrees celsius?

Specific heat of water is 4.18 Joules per gram per degree centigrade
--------------------
diff Temp = 21.6º C
m = 10 kg = 10000 grams.
-----------
joules = 4.18 j/gm/deg * 21.6 deg * 10000 gm (notice the units cancel)
= 902880 joules
= 902.88 kilojoules
