Properties of Matter Quizizz Review

Which statement describes the energy of the particles in this sample during interval DE?

• Both potential and kinetic energy increases

• Both potential and kinetic energy decreases

• Potential energy increases and the kinetic energy stays the same

• Potential energy remains the same and the kinetic energy increases

Answer explanation

When the temperature remains the same, the kinetic energy does not increase. The potential energy increases because the molecules have the POTENTIAL to speed up!

Which line segment represents an increase in average kinetic energy?

• AB and BC

• AB and CD

• BC and DE

• DE and EF

Answer explanation

As temperature/thermal energy increases, the average kinetic energy of the molecules within a substance also increases. The molecules SPEED up!

What is the density of the marble?

• 0.79 g/cm3

• 0.95 g/cm3

• 1.05 g/cm3

• 1.27 g/cm3

Answer explanation

To calculate density: D= m/v (mass divided by volume)

For irregular solids, you can use the water displacement method to find volume. The water in the graduated cylinder started at 10 mL. After dropping the solid into the water, the water level rose to 13 mL. 13-10= 3mL

Density= 3.8 g / 3 mL= 1.27 g/cm3

Which liquid inside the beaker has the greatest density?

• 1

• 2

• 3

• 4

Answer explanation

The greater the density, the more a substance will sink.

What is the melting point of the substance?

• 0

• 20

• 50

• 90

Answer explanation

On a heating curve, the lowest point is a solid. This is because solids have the lowest thermal energy and kinetic energy. Melting is when a solid changes into a liquid. Therefore, the temperature at which the solid begins to melt is during the line segment between a solid and liquid.

What state of matter is the scientist most likely observing?

• Solid

• Liquid

• Gas

• Plasma

Answer explanation

The molecules of a solid are condensed, meaning that they are very close together. As they are close, they are also vibrating at a slower speed when compared to other states of matter.

Nitrogen molecules within a glass tube are allowed to move randomly. Which figure shows the molecules in a state with the greatest amount of kinetic energy?

• 
• 
• 
• 

Answer explanation

The particles in jar C represent those of a gas. Gas molecules are spread further apart than those of solids and liquids. The speed of gases are the greatest, which means gas particles have the greatest kinetic energy.

Which of the following has caused the changes in pond A to B?

• The pond water has lost heat and energy

• The pond water temperature increased

• Warm water has risen to the top

• All the water has evaporated from the pond

Answer explanation

In pond A, the state of matter of the water is in a liquid form. In pond B, the water changes state and is now a solid. By going from a liquid to a solid, the kinetic and thermal energy of the molecules decrease.

Which of the following phase changes are the copper atoms undergoing?

• gas to liquid

• liquid to gas

• solid to liquid

• liquid to solid

Answer explanation

The molecules are condensed to begin with, which indicates that it is a solid state. Then, the molecules begin to separate but are still relatively close together and are able to flow past one another which indicates a liquid. So the change of state is a solid---liquid.

If a ball has a density of 1.78 g/cm3 and is placed into the beaker, then where will the ball come to a rest?

• on top of liquid A

• between liquids b and c

• between liquids c and d

• on the bottom of the beaker

Answer explanation

The greater the density, the farther down the object will sink. Since the density is less than 2.34 and greater than 1.21, then the object will rest in between these two liquids.
