What is the boiling point of heavy water?

  • A
    $100 \cdot 4^{\circ} \mathrm{C}$
  • Correct answer
    B
    $101 \cdot 4^{\circ} \mathrm{C}$
  • C
    $273^{\circ} \mathrm{C}$
  • D
    $100^{\circ} \mathrm{C}$

Solution

Correct answer is $101.4^{0} \mathrm{C}$ The boiling point of heavy water is $101.4^{0} \mathrm{C}$ or $374.4 \mathrm{~K}$. Its melting point is $3.8^{0} \mathrm{C}$ or $276.8 \mathrm{~K}$.

Hence, the correct answer is option: 'B'.
