Janelle is observing a sample of matter. She notes that it is a shiny silver-colored solid, has a

mass of around 20 grams, and conducts heat and electricity well. What type of properties is

Janelle observing?

Chemical properties

Only intensive properties

Physical properties

Only extensive properties

Janelle is observing Physical properties.

Why?

The properties of matter can be classified as follows:

Extensive and Intensive: Extensive properties depend on the amount of matter involved in the measuring (e. g. mass), and intensive properties do not depend on the amount of matter (e. g. density, conductivity). Physical and Chemical: Physical properties do not involve a change in the nature of the substance that is being measured (e. g. color, length), while Chemical properties involve a change in the nature of the substance when they are measured (e. g. reactivity).

The properties that Janelle observed are: Color (intensive, physical), mass (extensive, physical), heat conductivity (intensive, physical), and electrical conductivity (intensive, physical). All these properties are Physical properties.

Have a nice day!
