Sample questions

1. Which of the following is an example of matter?

   1. Heat
   2. Light
   3. Sound
   4. A book
   Show answer

   Answer: D. A book

   Matter is anything that has mass and takes up space. Heat, light, and sound are forms of energy, not matter. A book has mass and occupies space.

2. What is the process called when a gas changes into a liquid?

   1. Evaporation
   2. Melting
   3. Condensation
   4. Sublimation
   Show answer

   Answer: C. Condensation

   Condensation is the change of the physical state of matter from the gaseous phase into the liquid phase. It is the reverse of vaporization (evaporation).

3. When ice melts into water, what property of matter is changing?

   1. Chemical composition
   2. State
   3. Number of atoms
   4. Mass
   Show answer

   Answer: B. State

   Melting is a physical change that alters the state of matter from solid to liquid, but the chemical composition (H2O) and the number of atoms remain the same.

4. Which of the following is a pure substance?

   1. Ocean water
   2. Brass (an alloy of copper and zinc)
   3. Distilled water
   4. Air
   Show answer

   Answer: C. Distilled water

   A pure substance is a single element or a single compound. Distilled water (H2O) is a compound. Ocean water, brass, and air are mixtures.

5. Which state of matter has particles that are spread out and move in random, straight lines until they collide with something?

   1. Solid
   2. Liquid
   3. Gas
   4. Plasma
   Show answer

   Answer: C. Gas

   Gas particles possess high kinetic energy, move independently of each other, and are far apart, filling the entire volume of their container.
