Front

What is the Kinetic Theory of Matter?

Back

The Kinetic Theory states that matter is made up of particles which are in continual random motion.

Front

What are physical properties of matter?

Back

Physical properties are characteristics that can be measured or observed without changing the substance's chemical identity, such as density, melting point, and boiling point.

Front

What is matter?

Back

Matter is anything that has mass and takes up space.

Front

What are chemical properties of matter?

Back

Chemical properties are characteristics that can only be observed when matter undergoes a change to become an entirely different kind of matter.

Front

What is the melting point?

Back

The melting point is the temperature at which a substance changes from solid to liquid.

Front

What is density?

Back

Density is the mass of a substance divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

Front

What is boiling point?

Back

The boiling point is the temperature at which a substance changes from liquid to gas.

Front

What is the difference between physical and chemical properties?

Back

Physical properties can be observed without changing the substance, while chemical properties can only be observed during a chemical change.

Front

What is an example of a physical change?

Back

An example of a physical change is ice melting into water.

Front

What is an example of a chemical change?

Back

An example of a chemical change is rust forming on iron.
