Inert Gas of the week

Helium

What is an inert gas? 

An inert gas is a gas which does not undergo chemical reactions under a set of given conditions. 

Helium is a inert gas. Helium is a very light, inert, colorless gas. Helium has the lowest melting point of any element. It is the only liquid that cannot be solidified by lowering the temperature. It remains liquid down to absolute zero at ordinary pressures, but can be solidified by increasing the pressure. The specific heat of helium gas is unusually high. Next to hydrogen helium is the most abundant element in the universe. 

I mostly associate helium with blowing up balloons and people putting the gas in their mouth to sound funny.
