Avogadro's Hypothesis

Avogadro's hypothesis says that if pressure and temperature are the same then...

• equal volumes of gas will have an equal number of particles

• smaller particles will occupy less volume

• the identity of the gas determines the volume

• equal volumes of gas will have a number of particles that depends on whether they are elements or compounds

A particle that is made by combining two atoms is called

• diatomic

• diparticulate

• biatomic

• biparticle
