In the case of the inert gases, all is different.

Why is there a big increase for the inert gases?

A. In my day, we called them the inert gases.

They do this by using an inert gas as the conductor between the two lines.

They are sometimes referred to as the inert gases too.

Inert gases can also be made of more than one element.

Lines not being used are filled with nitrogen, an inert gas.

Nitrogen is often used as an inert gas in the chemical industry.

Probably the interior had been sealed and filled with inert gas until recently.

The report went on to suggest that an inert gas be pumped into the space above the fuel.
