What is a physical change in matter? Molecules can move from one physical state to another (phase change) and not change their atomic structure.Oxygen (O 2) gas has the same chemical properties as liquid oxygen.The liquid state is colder and denser (less energy),but the molecules are the same.Chemical and Physical Properties and Changes.docx Physical Changes (If it melts or goes to the gas phase) Chemical Changes (If it burns,its a chemical change) Sucrose,C 12 H 22 O 11 White Odorless 210 g/100 ml (25 °C) Soluble Decompose Goes to the gas phase no new chemical bonds are formed NaCl white crystalline solid with a density of 2.16 g/mL,and a melting point of 801 °C 25 °C is Clathrate Hydrate Physical Property DatabaseClathrate Hydrate Physical Property Database NIST Standard Reference Database # 156.Developed by K.Kroenlein,C.D.Muzny,A.Kazakov,V.V.Diky,R.D.Chirico,E.D.Sloan and M.Frenkel under contract DE-AI26-06NT42938 for the National Energy Technology Laboratory,U.S.Department of Energy Thermodynamics Research Center (TRC)
