### Physical properties review

1. 1. Physical Properties <br />Review 4<br />
2. 2. Physical Properties 1 <br />Which of the following could be a description of a compound forming?<br />Heat energy added to liquid causes it to evaporate. <br />Two metals are melted together to produce a solution. <br />A clear crystal dissolves in a beaker of water.<br />The interaction of a green gas and a metallic solid produces a white crystal. <br />

6. 6. Physical Properties 3 <br />Which of the following best describes the interaction between the particles that make up a liquid?<br />The particles are loosely connected and can only vibrate. <br />The particles can move independently and collide frequently. <br />They particles can move past each other and are loosely connected<br />The particles are locked in position and often collide. <br />

8. 8. Physical Properties 4<br />Which of the following is an example of a chemical reaction?<br />The combination of a magnetic metal and a clear gas makes a non-magnetic solid. <br />Two powdered solids are mixed together and then separated by water and filter paper. <br />The fast moving particles of a substance slow down to form an orderly, repeating pattern. <br />A liquid evaporates, leaving behind a chalky paste. <br />
