What is point two of the particle theory? | Particles have empty spaces between them |
What is point three of the particle theory? | Even though you cannot see them, particles are moving randomly all the time |
What is point four of the particle theory? | Particles move faster and spread farther apart when they are heated |
What is point five of the particle theory? | Particles attrcat each other, so they tend to stay together rather than fly apart |
