Chemical and Physical Properties

Physical properties A physical property is a characteristic of a substance that can be observed without changing the substance into another substance. (You can see it without changing what you’re looking at into something else.)

Physical Properties - Examples Examples physical properties include: Volume Mass Weight Size Density Melting point Boiling point Density = mass per volume

Physical Properties - Examples Other physical properties include: Color Hardness Odor Taste State of matter Texture Luster (shine) Flexibility Heat conductivity Electrical conductivity Solubility Shape Viscosity Ductility Malleability Luster = shine Flexibility = ability to move Solubility = ability to dissolve in water Viscosity = liquid thickness Ductility = ability to stretch into a wire Malleability = ability to form a thin sheet by hammering or rolling

Physical properties List as many physical properties as you can for this item Color – white Solubility – can dissolve in water Taste – sweet Heat conductivity – poor Shape – cube Texture - grainy

Chemical properties A Chemical property is a characteristic of a substance that can only be observed by changing it into a different substance.

Chemical properties - Examples Examples of chemical properties include: The ability to burn Ability to tarnish Ability to rust Ability to decompose Ability to react with other chemicals Instability Ability to do acid/base reactions Tarnish = corrosion form over metal Decompose = break apart chemically Instability = the state of being likely to change
