Helium Properties - What are the Physical Properties of Helium?
What are the Physical Properties of Helium? The Physical properties of Helium are the characteristics that can be observed without changing the substance into another substance. Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. The Physical Properties of Helium are as follows:
What are the Physical Properties of Helium?
When cooled it condenses to liquid helium. Liquid helium is the only element that does not solidify at normal pressure regardless of the temperature
|Density||Helium is less dense than any other known gas except hydrogen and is about one seventh as dense as air|
|Odor||It is odorless|
|Viscosity||Extremely low viscosity (resistance to flow - stickiness)|
|Compounds||Helium is completely inert. It does not form compounds or react with any other element|
Helium Properties - What are the Chemical Properties of Helium?
What are the Chemical Properties of Helium? They are the characteristics that determine how it will react with other substances or change from one substance to another. The better we know the nature of the substance the better we are able to understand it. Chemical properties are only observable during a chemical reaction. Reactions to substances may be brought about by changes brought about by burning, rusting, heating, exploding, tarnishing etc. The Chemical Properties of Helium are as follows:
What are the Chemical Properties of Helium?
|Reactivity with water||It is less soluble in water than any other gas|
|Flammability||It is non-flammable|
