You will identify unknown substances and learn that physical properties are characteristics of materials.
After completing this tutorial, you will be able to complete the following:
A physical property is a characteristic of a substance that does not change based upon the amount of the substance. Physical properties include ductility, color, boiling point, freezing point, malleability, density, melting point, and water solubility, among others. Physical properties such as density, melting point, and water solubility are usually distinctive and can be used to identify substances. This Activity Object explores density, melting point, and water solubility and engages learners in using those physical properties in order to identify eight unknown substances.
