Question

1. matter is anything that has mass and volume. the 2 states of matter that occupy a definite volume are solid and liquid. 2. physical and chemical are the other 2 states of matter. 3. changes do not changes alter the identity of a substance, whereas 4. answer the following question in the space provided. 5. what is the relationship between the kinetic energy of molecules and their physical state?

Explanation:

Step1: Recall matter definition

Matter has mass and volume.

Step2: Identify matter states

Solid and liquid have definite volume.

Step3: Differentiate changes

Physical changes don't alter substance identity, chemical changes do.

Step4: Understand kinetic - state relation

Higher kinetic energy, more fluid - like state.

Answer:

1. Matter
2. Liquid, Solid
3. Physical, Chemical
4. Physical
5. Higher kinetic energy corresponds to more fluid - like physical state.
