Phase changes worksheetname fill in the phase changes in the blank provided. 14. 13. 12. time of added for each number indicate: a) what phase or phases are present? b) is a phase change taking place? if so name the phase change. c) is energy be added or released? d) is potential energy increasing, decreasing or staying the same?. Between 9 and 13 minutes, the added energy increases the temperature of the substance. during the time from point d to point e, the liquid is vaporizing. by point e, the substance is completely in the gas phase. material in this phase has indefinite volume and shape. the energy put to the substance between minutes 13 and 18 converted.

This heat energy is called the latent heat of fusion. between 9 and 13 minutes, the added energy increases the temperature of the substance. during the time from point d to point e, the liquid is vaporizing. by point e, the substance is completely in the gas. phase. material in this phase has infinite volume and infinite shape. Between 9 and 13 minutes, the added energy increases the of the substance. during the time from point d to point e, the liquid is . by point e, the substance is completely in the phase. material in this phase has volume and shape. the energy put. Unit 2: phase changes worksheets phases of matter: solid matter that has definite volume and shape. the molecules are packed together tightly and move slowly. liquid matter that has definite volume but not shape. since the molecules of a liquid are loosely packed and move with greater speed, a liquid can flow and spread out. gas. %pdf 1.4 %âãÏÓ 51 0 obj > endobj 58 0 obj > filter flatedecode id[7b01907ceadb5144c3ccad7a649f5150>99597b47dd3e204b95be34bf0bdfd728>] index[51 9] info 50 0 r.
