What is the boiling point of heavy water?

What is the boiling point of heavy water?
  1. $100 \cdot 4^{\circ} \mathrm{C}$
  2. $101 \cdot 4^{\circ} \mathrm{C}$
  3. $273^{\circ} \mathrm{C}$
  4. $100^{\circ} \mathrm{C}$

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 $276.8 \mathrm{~K}$.
