Phase Changes

Warm Up: Matching Temperature Measure of the kinetic energy in an object Heat Form of energy that is transferred between systems or objects with different temperatures The heat energy from water is transferred to the cold ice, melting the ice correct description of heat transfer The cold energy from the water is transferred to the hot water, cooling the water incorrect description of heat transfer #1.) What is the relationship between molecular movement and temperature? As temperature increases, molecular movement increases. As temperature increases, molecular movement decreases. There is no relationship between temperature and molecular movement. #2.) Sort each phrase under the phase change. Melting Solid to Liquid Also called liquefying Freezing Liquid to Solid Also called solidifying Condensation Gas to Liquid Water forms on the side of a soda can. Evaporation Liquid to Gas It rains in the morning, but the sidewalk is dry by the afternoon. Deposition Gas to Solid Snow forming is an example. Sublimation Solid to Gas Dry ice is an example. #3.) Label the phase change graph using the terms below. Do not use any capital letters. melting boiling solid liquid gas melting point boiling point melting point boiling point solid melting liquid boiling gas #4.) Using the graph in #3, describe what is in the beaker after 5 minutes. ice only ice and water water only water and gas Using the graph in #3, how long did it take the ice to melt? 7 minutes 17 minutes 5 minutes 2 minutes Ext Ticket: Describe the energy of ice particles as it goes through the following phase changes:Ice to waterWater to water vapor
