The Particle Theory

QuestionAnswer
List the 5 main points of the particle theory 1. All matter is made up of tiny particles 2. Particles have empty spaces between them 3. Even though you can't see them, particles are moving randomly all the time 4. Particles move faster and spread further apart when heated 5. Particles at
What is the particle theory? The particle theory is an explanation of what matter is made up of and how it behaves. The particle theory states that all matter is made up of tiny particles that are always moving, that attract each other, and that have space between them.
Do solids have a definite shape and/or volume? Solids have a definite volume and shape unless the temperature changes (e.x. Ice when heated it turns to water)
Do liquids have a definite shape and/or volume? Liquids have a definite volume but not a definite shape because it takes the shape of it's container
Do gases have a definite shape and/or volume? Gases do not have a definite shape or volume. Like liquids gases will take the shape of it's container, but will also take the volume of the container as well.
Why does ice melt when it's heated? When ice is heated it's particles start to move faster and more freely and ice turns back to it's liquid form.
Why does liquid water turn into steam when heated? More heating makes the particles move even faster and farther apart and liquid water turns into gas.
