Matter Review

What is the best way to find out if an apple has more mass than a baseball?

• place a magnet next to each object, and see which object the magnet attracts.
• Put one object in each pan of a balance; the pan with more mass in it will move lower than the other pan. 
• Give each object an equal push; the one with more mass will move further.
• Look at the size of each object; the larger object has more mass.

Which physical property is used to identify matter based on solubility?

• Ability to evaporate
• Volume
• Ability to dissolve
• Mass

Picture is an example of what? 

• The water has more density than the ice cubes.
• The ice cubes are freezing in the water. 
• The ice cubes are resting at the bottom of the glass
• The ice cubes are melting and becoming a liquid. 

Which of these materials would NOT be a good insulator of electricity? 

• Metal
• Glass
• Plastic
• Wood

Based on the properties, which of the following materials is a solid, not attracted to magnets, and soluble in water. 

• Iron Nail
• Salt
• Sand
• Penny

A glass beaker is placed on a hot plate. Five hundred milliliters of room temperature water are added to the beaker. If the temperature continues to increase, the water in the beaker will most likely- 

• turn into a solid
• become more dense
• turn into a gas
• show no change in temperature 

Water changes its state of matter when heat is added or taken away. When water reaches its boiling point the particles- 

• are close together
• stay the same
• are moving more rapidly
• are moving more slowly

A student places a cup of water in the freezer and leaves it there overnight. The next morning the student observes that the water in the cup has changed to ice. Which of the following statements best concludes why the water changes to ice? 

• The water gains energy
• the water reaches its boiling point
• the volume of the water decreases
• heat is taken away from the water
