25)  List the statements that are included in the particle theory of matter:

1. All matter is made up of tiny particles called atoms

2. Particles of matter are constantly in motion

3. Particles of matter attract each other

4. Particles of matter have space between them

5. As temperature increases the particles of matter move faster

27) Define compound- A substance made up of 2 or more elements chemically combined in a specific ratio

 

28) Define mixture- 2 or more substances that are together in the same place but their atoms are not chemically bonded

 

29)  Define element-a pure substance that can’t be broken down into other substances by chemical or physical means
