Physical properties are the properties of an object that can be observed.
For example color, shape, and texture are all physical properties. For practice place an unlit candle in front of you and write down 5 of its physical properties. Chemical properties describe how a substance changes into a new substance. For example, you know from previous experience that wood has the ability to burn, therefore since wood changes chemically when it burns, one of its chemical properties is its ability to burn. Water on the other hand does not burn so water does not have the chemical property of burning.
