Explanation

The freezing point of heavy water is 3.82°C:

| | Heavy water (D2O) | Regular water |

|---|---|---|

| Freezing point | 3.82°C | 0°C |

| Boiling point | 101.42°C | 100°C | 

Heavy water is made up of two deuterium atoms and one oxygen atom.

It contains more deuterium, a hydrogen isotope, than regular water, which contains hydrogen-1.

Heavy water is used in reaction mechanisms.

It is is prepared by electrolyzing water.

Explanation

The freezing (or melting) point of ice on the Fahrenheit scale is 32°F.

This is the temperature at which ice turns from a solid to a liquid. 

The Fahrenheit scale also defines the boiling point of water as 212°F.

A change of 1°F on the Fahrenheit scale is less than a 1°C change on the Celsius scale.

Explanation

The element required for solar energy conversion is silicon: 

Silicon is the most common semiconductor material: Silicon is used in about 95% of solar cells sold today. 

Silicon is a naturally occurring element: Silicon is the second most abundant element on Earth, after oxygen
