Can someone explain to me how to solve this?

Hi!

Is the answer A)?

The specific heat capacity of water is equal to 1 calorie (4184 J).

One calorie is the amount of energy required to raise 1 gram of H2O by 1°K or 1°C.

(I’m not sure if this statement is true since the question states the units are kg not g??)

In 200L of water we have 200kg.

200 * 4184 = 837200 kg/K

EDIT: one nutritional calorie, or Calorie with a capital C, is the amount of energy to heat 1 KG of water by 1°C. This statement is the correct one to help solve the question.

Hope this helps!

Hi, this might sound irrelevant but could you please tell me which site is this?
