Across
- 2. the flow of thermal energy into and out of a substance
- 4. point A physical property of matter that is described as the point in which the energy of a substance increases, and its particles increase in their movement causing the substance to change from a solid to a liquid
- 6. a physical property that describes the physical form in which matter exist-solid, liquid, gas, or plasm
- 7. point A physical property of matter and a temperature specific to the substance that is described as the point in which the energy of a substance decreases, and its particles decrease in their movement causing the substance to change from a liquid to a gas
- 9. point A physical property of matter and a temperature specific to the substance that is described as the point in which the energy of a substance decreases, and its particles decrease in their movement causing the substance to change from a gas to a liquid
- 11. particles slide/glide past each other staying in contact and having a definite volume but taking the shape of the container it’s in
- 12. particles bounce off each other and low attraction to each other and having NO definite shape and NO definite volume spreading out to fill the container it’s in
- 15. A physical change of matter in which the energy of a liquid increases to the point that the liquid changes into a gas with the same chemical formula. In other words, the state of matter changes but not the make-up of the substance. This physical change occurs throughout the liquid and as gases are formed, they rise to the top of the liquid.
- 16. A physical change of matter in which the energy of a liquid increases to the point that the liquid changes into a gas with the same chemical formula. In other words, the state of matter changes but not the make-up of the substance. This physical change occurs at the surface of a liquid.
Down
- 1. the measure of the average thermal energy in a substance
- 3. energy the energy of moving particles – the faster they move the more of this type of energy the particles have
- 5. a physical change in which the thermal energy of a substance decreases, the particle movement slows, and the substance changes from liquid to solid.
- 8. A physical change of matter in which the energy of a gas decreases and the gas particles move closer together to the point that the gas changes into a liquid with the same chemical formula. In other words, the state of matter changes but not the make-up of the substance.
- 10. particles that have so much energy that their electrons begin to separate from the atoms; having no definite volume and no definite shape these substances are often very hot
- 13. particles vibrate in place, having a definite shape and definite volume
- 14. point A physical property of matter and a temperature specific to the substance that is described as the point in which the energy of a substance increases, and its particles increase in their movement causing the substance to change from a liquid to a gas
