virial

1 9.9

A number that shows how gas or liquid particles interact

noun
/ˈvɪrɪəl/

Specialized

: coeficiente virial

The virial coefficient is crucial for understanding gas interactions in the virial expansion.

Examples

And we saw that by doing that I can gradually construct a virial expansion that is appropriate for these gases.
In the study of liquids, the virial is used to calculate the forces between particles in equilibrium.
Researchers often analyze the virial to understand the thermodynamic properties of complex fluids.

Etymology

Virial comes from the Latin root vis meaning 'force' or 'power'. A helpful way to remember the thermodynamics use is to think of a virial coefficient as a number that shows how much particles 'push' or 'pull' each other in a gas.
