Physical Science Quiz

1. What are the basic building blocks of matter?

Molecules
Atoms
Elements
Compounds

2. What is the relationship between mass and the number of atoms in an object?

The more atoms in an object, the greater its mass
The more atoms in an object, the lighter its mass
There is no relationship between atoms and mass
Mass is determined by volume, not atoms

3. Look at the phase diagram below that shows the states of matter for a substance at different temperatures and pressures. What can you infer will happen if you follow path X?

The substance will change directly from solid to gas
The substance will melt from solid to liquid
The substance will freeze from liquid to solid
The substance will remain in the same state

4. What is formed when atoms bond together?

An element
A molecule
A force
Energy

5. The graph below shows the motion of two objects of different masses falling toward Earth. Based on this data, what can you infer about gravity's effect on objects with different masses?

Heavier objects fall faster than lighter objects
Lighter objects fall faster than heavier objects
Objects of different masses fall at the same rate in a vacuum
Objects don't fall unless they have magnetic properties

6. According to the chapter, what is energy?

Another term for matter
When atoms are bonded together
When force is applied to matter
A type of element

7. According to the chapter, what happens when an object with less mass is near an object with greater mass?

Nothing happens unless they touch
The smaller object will move faster toward the larger object
The larger object will move faster toward the smaller object
Both objects repel each other

8. According to the chapter, which of the following is described as a natural force that "happens without any intervention from anything else"?

Gravity
Mechanical energy
Chemical bonds
Phase changes

9. What causes matter to exist in different phases?

The number of atoms it contains
The temperature and pressure of its environment
The type of molecules it forms
Its position relative to Earth

10. What is a universal law in science, according to the chapter?

A rule that only applies on Earth
A prediction that takes into account an object's mass, composition, and speed to predict interactions
A theory that cannot be proven
A mathematical equation invented by scientists
