What is the freezing point of heavy water (deuterium oxide)?
(A) 3.82°C
(B) 2.82°C
(C) 1.82°C
(D) 0.82°C
The freezing point of heavy water, or deuterium oxide (D₂O), is 3.82°C or 38.88°F. This value is higher and above that of regular water, which has a freezing point of 0°C, or 32°F. This anomaly occurs because of the differing weights of deuterium and hydrogen.
