Step-by-step explanation:

The heat capacity of water is 1 calorie for 1 gram raised 1 degree C

or 4.186 joules of energy for 1 gram raised 1 degree C ( or

= 100000 grams of water.

It takes 10 000 calories to raise 10 000 grams of water 1 degree

so 20 degrees x 10 000 grams = 2 000 000 calories.

The same type calculations can be done for heat in joules

10, 000 grams x 4.186 joules x 20 degrees. = 8372000 joules.
