Scope 1 Test Review: Solids, Liquids, and Gases

Which of the following statements correctly compares the atomic structures of solids and gases?

• Particles in solids are loosely packed and can move around, while particles in gases are arranged in a tight, repeating pattern.

• Particles in solids are arranged in a tight, repeating pattern, while particles in gases are loosely packed and can move around. 

• Particles in solids can move around more easily than those in a gas. 

• Particles in gases are packed more tightly than those in a solid. 

The kinetic energy of atoms in solids– 

Responses

• is lower than liquids but higher than gases. 

• is higher than liquids but lower than gases. 

• does not exist. Only liquids and gases have kinetic energy. 

• is much lower than the energy in liquids and gases.

Which statement best compares the shapes of liquids and gases? 

Responses

• 
  

• Liquids take the shape of their containers, while gases spread out and do not take the shape of the container. 

• Liquids never take the shapes of their containers, while gases usually do. 

• Particles in a liquid form a straight line, and particles of a gas do not. 

• The particles in a liquid have a definite shape, while those in gases do not. 

What happens to the kinetic energy of the atoms in a liquid as it is cooled, and how does their movement change?

• The atoms move slower, and the liquid becomes a gas. 

• The atoms move faster, spread out, and become a gas. 

• The atoms begin moving faster, and the substance becomes a solid. 

• The atoms move slower, and they take on a more regular structure.

As liquid water boils, what happens to change the volume of the substance? 

• As heat energy is taken away, the volume of the water becomes more definite. 

• The heat energy causes the molecules to move more slowly and clump together, taking up less space. 

• Heat energy causes the molecules to move faster, so they are farther apart and take up more space. 

• The molecules grow larger and take up more space, so the volume increases.

Which two characteristics describe the particles of matter in a gaseous state? 

• Only gases will change volume to fill the container. 

• The particles have a definite structure but do not take the shape of the container. 

• The particles have less energy than solids. 

• The particles are not arranged in a particular structure and flow freely. 

• The particles behave exactly like those in liquids. 

Which of the following best describes the movement of particles in a solid?

Responses

• Particles in a solid move freely and are far apart. 

• Particles in a solid vibrate in place and are closely packed. 

• Particles in a solid move rapidly and are loosely packed. 

• Particles in a solid move in straight lines and are far apart. 

How does the temperature of a substance affect the kinetic energy of its particles?

Responses

• As temperature increases, the kinetic energy of the particles decreases. 

• As temperature decreases, the kinetic energy of the particles increases. 

• As temperature increases, the kinetic energy of the particles increases. 

• Temperature has no effect on the kinetic energy of the particles.
