States of Matter and Phase Changes

Master states of matter & phase changes! Explore kinetic theory, energy, and properties.

Fill in the blank with the correct words related to Kinetic Theory 1. Gas particles move in a random pattern. They move rapidly2. Liquid particles move around, but move slowly3. Solid particles only vibrate in the same position4. Particles move faster when there is more heat5. Particles move slower when there is less heat Identify each state of matter A Gas B Solid C Liquid Sort the characteristics as either solid, liquid, or gases. Solid particles closely packed lowest energy particles only vibrate fixed volume and shape Liquid some energy particles slide past each other fixed volume but not shape Gas highest energy particles are in constant motion Does not have fixed volume or shape Molecules in Matter Draw a picture of the molecules in each state of matter Match each phase change description to its name solid to liquid melting liquid to gas vaporization solid to gas sublimation gas to liquid condensation liquid to solid freezing gas to solid deposition Examples Give an example of each phase change in the table below: Phase Change Example Freezing Melting Evaporation Condensation Sublimation Deposition Fill in the blanks: 1. In an exothermic reaction, energy is removed2. In an endothermic reaction, energy is added3. Melting ice (solid to liquid) is an endothermic reaction4. Condensation (gas to liquid) is an exothermic reaction Sort the properties between intensive and extensive properties Intensive Color Hardness Luster Boiling Point Extensive Volume Size Mass Length
