336,000J
672,000J
8,704,000J
9,040,000J
9,376,000J
Correct answer is C
\(Q_{s} - Q_{w} = (4 \times 2260000) - (4 \times 4200 \times (100 - 80))\)
= \(9040000 - 336000\)
= \(8,704,000 J\)
Which of the following statements about the circulation of blood is not correct?
Deoxygenated blood flows in the heart through the vena cavae
