Heavy water is approximately than ordinary water. Appearance : Colorless and odorless liquid. Freezing/Boiling Points : It freezes at ) and boils at

: Because it is denser, ice cubes made of heavy water will sink in a glass of ordinary liquid water. 2. Primary Uses Heavy Water

: It slows down neutrons in nuclear reactors without absorbing them. This allows reactors like the Canadian CANDU design to use natural uranium rather than expensive enriched uranium. Heavy water is approximately than ordinary water

Deuterium occurs naturally but is rare—only about hydrogen atoms in ocean water is deuterium. Deuterium occurs naturally but is rare—only about hydrogen

Heavy water's most famous application is in the nuclear industry, but it serves several high-tech roles:

: Large quantities are used in specialized detectors, such as the Sudbury Neutrino Observatory , to study solar particles.
