Answer and explanation
Correct answer: C. 126000
- Step 1: Use the specific heat capacity formula: .
- Step 2: Substitute water specific heat , mass , and temperature change : .
- Step 3: Calculate the total required heat energy: .
Answer
126000.
Why not the others: 63000, 252000 and 30 do not fit.
