13. Energy in the form of heat that is transferred from a hot place to a cold place
15. two or more atoms joined together
16. matter with a fixed volume and shape, and lower energy/movement

1. stored energy
2. Energy from the movement of an object from one place to another
3. the amount of SPACE an object or substance takes up
4. a state of matter with a defined volume but no defined shape and whose molecules slide/glide past each other with medium energy
6. a state of matter without any defined volume or shape in which atoms or molecules move about freely with high energy
7. material (or STUFF) that has mass and takes up some amount of space (volume)
8. the force of gravity on an object (it is equal to mass x gravity)
12. the smallest unit of an element that has the properties of that element. It contains protons, electrons, neutrons, and a nucleus.
