- 3. Multiple Choice
The phase change from water vapor to liquid water is known as...evaporationprecipitationcondensationsublimation - 4. Multiple Choice7. All phase changes (changing states) requires energy to be added or taken away.TrueFalse
- 5. Multiple ChoiceWhat happens to particles when they are heated?They speed up and spread outThey slow down and compressThey stop movingThey move closer together and speed up
- 6. Multiple ChoiceAll changes in the state of matter of a substance requiresvibrationwaterpermissionenergy
- 7. Multiple ChoiceHow are solids different from liquids?particles in solids are moving freely around each other.particles in solids have no motion.particles in solids are vibrating in place.particles in solids have more motion than in liquids
- 8. Multiple ChoiceA gashas a definite shape but no definite volumehas a definite volume but no definite shapehas fast-moving particles
- 9. Multiple ChoiceBased on the heating curve, what happens to the particles within a substance as it changes from a liquid to a gas?When changing to a gas, the particles within a substance break free of each other, move randomly and freely, with no defined volume.As the temperature decreases, the particle vibrations within a substance increases, causing them to move faster and more freely.When changing to a gas, the particles within a substance slide past each other, move randomly and freely, with a defined volumeIntermolecular forces hold the particles within the substance close together during the phase change.
- 10. Multiple ChoiceAccording to the heating curve, when a substance is melting, what is happening to the temperature as energy is continually being added it?The temperature is increasing as more energy is being added to melt the substance.The temperature stays the same as energy continues to be added to melt the substance.The temperature is decreasing as more energy is being added to melt the substance.The flat curve indicates a change in the temperature allowing for a change in phase.
