What is the boiling point of heavy water?

What is the boiling point of heavy water?

Options

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

Correct answer

B. $101 \cdot 4^{{}^{{}^{\circ}}} \mathrm{C}$

Step-by-step 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}

.
