What is an ideal gas?

A gas whose volume varies in proportion to the temperature and in inverse with the pressure

What are the kinetic assumptions when dealing with an ideal gas?

* The gas contain a large number of molecules moving in random directions and speeds
* Electrostatic forces between molecules is negligible, except during collisions
* Collisions are perfectly elastic
* Time of collisions between molecules is negligible
* Molecules of gas occupy negligible volume compared to the total volume of gas

What are the ideal gas conditions?

* Low pressure
* High temperature

How do you ideal gasses act at low temperatures and high pressures?

* Intermolecular forces are no longer negligible
* Molecular size is no longer negligible

What is the ideal gas equation?

pV=nRT

What is the equation linked with ideal gasses to find Mr?

M=mRT/pV

What is an allotrope?

Different forms of an element of the same state

Describe the structure of fullerene

Lattice structure

What is a nanotube?

A single sheet of carbon atoms covalently bonded to each other
