identify whether each of the following statements is true regarding the particle theory of matter and the phases of matter. mark t for true and f for false. 1. _____ the particles in a solid do not move at all. 2. _____ particles in a liquid have more energy than those in a solid. 3. _____ all matter is made up of tiny particles called atoms. 4. _____ if you have two different substances, the particles in those substances will be identical. 5. _____ particles in a gas have the least amount of energy. 6. _____ particles in a substance naturally repel each other. 7. _____ liquids take the shape of their container, but have a fixed volume.
Answer
Brief Explanations:
- In a solid, particles vibrate in place, not completely stationary. So it's false.
- Liquid - state particles have more kinetic energy than solid - state particles as they can move more freely. So it's true.
- All matter is made up of tiny particles which can be atoms, molecules or ions. So the statement is false as it's too restrictive.
- Different substances have different types of particles. So it's false.
- Gas - state particles have the most energy as they move freely and rapidly. So it's false.
- Particles in a substance are attracted to each other, not repel. So it's false.
- Liquids take the shape of their container due to the ability of their particles to move and have a fixed volume as the particles are close together. So it's true.
