The molar heat capacity of water at constant pressure is . How much heat is required to raise the temperature of of water from to ?
Answer and explanation
Correct answer: D.
- Step 1: Find the number of moles of water: .
- Step 2: Calculate the temperature difference: .
- Step 3: Calculate the required heat: .
Answer
.
Why not the others: doubles the temperature change or moles; computes heat for only a rise; halves the correct quantity using .
