What does the small red circles in the diagram represent? 

Proton

300

Mixtures can be dived into two groups, what are they? 

Homogeneous and Heterogeneous 

400

How do you calculate density?

Mass Divided by Volume 

500

How does the saying "hot air rises" relate to the concept of density?

Hot has more energy and the particles are spread further apart making it less dense. Less dense things rise to the top. Therefore hot air rises about the cooler air below.
