Matter and Change

5. Very high kinetic energy. Particles collide with enough energy to break into charged particles (+/-).
6. A type of element that has the properties of both metals and non metals.
7. A law of matter that states that during a chemical reaction, the number and type of atoms remain the same.
9. Type of energy in motion.
10. Anything with mass that occupies space.
12. Very low kinetic energy. Particles vibrate but cannot move around.
13. High kinetic energy. Particles can separate and move throughout the container.

1. A process that releases energy into the surroundings.
2. The study of the composition, structure, and properties of matter and the changes it undergoes.
3. A type of element that are usually gases, solids are brittle, and are poor conductors of electricity and heat.
4. A process that absorbs energy from the surroundings.
5. Type of energy possessed by an object due to its position, composition, or condition
8. Low kinetic energy. Particles can move around, but are still close together.
10. A type of element that is solid at room temperature, malleable, ductile, and conduct electricity and heat well.
11. The capacity to do work or transfer heat.
