How much heat (in J) is needed to raise the temperature of of water by ? (specific heat of water )

Answer and explanation

Correct answer: D. 168000

  1. Step 1: The thermal energy required to elevate the temperature of a mass without phase change is calculated using .
  2. Step 2: Substitute mass , specific heat capacity of water , and : .
  3. Step 3: Multiplying the factors gives .
Answer
168000.
Why not the others: 84000 calculates heat for instead of ; 336000 doubles the required heat; 40 computes omitting specific heat capacity .
