AKS 5 - States of Matter

AKS 5

Multiple Choice

Eat at Joe's! Did you know that this neon sign is experiencing a change of state? When a neon sign lights up, like the one you see here, something is happening to the neon atoms inside the tube. How is this colorful sign related to kinetic energy and phase change?

• The electrical current in the tube generates the neon gas that glows in the dark.

• Electrical energy excites the neon atoms. They spin faster in the tube producing electromagnetic waves that we see as colors.

• Neon atoms accelerate once electrical energy is turned on to the tube. The faster the atoms move in the tube, the brighter the glow we see.

• Electrical energy accelerates the electrons in the neon gas. The gas ionizes and becomes plasma, containing both positive and negative ions.

Multiple Choice

In which state of matter are the particles CLOSEST together?

• gas

• solid

• liquid

• plasma

Multiple Choice

Of the following states of matter, plasma MOST closely resembles

• solid

• liquid

• gas

• none of the above

Multiple Choice

What is the difference between the plasma and gaseous states of matter?

• The gaseous and plasma states are electrically neutral.

• The gaseous state is electrically positive, while the plasma state is electrically negative.

• The gaseous state is electrically negative, while the plasma state is electrically negative.

• The gaseous state is electrically neutral, while the plasma state can be either electrically positive or negative.

Multiple Choice

The circle on the left shows a magnified view of a very small portion of liquid water in a closed container. What would the magnified view show after the water evaporates?

Multiple Choice

Solids are often defined as having a definite shape, while gases and liquids have no definite shape. This can best be explained by the fact that

• solids have a more ordered arrangement of atoms than liquids and gases.

• in solids molecules move faster than in liquids or gases.

• solids have less internal energy than liquids and gases.

• solids have the least orderly internal structure.

Multiple Choice

Relate the changes in molecular motion of particles as they change from solid to liquid to gas.

• As the phase changes occur, the freedom of motion of the particles increases.

• As the phase changes occur, the freedom of motion of the particles decreases.

• As the phase changes occur, the freedom of motion of the particles compresses.

• As the phase changes occur, the freedom of motion of the particles is constant.

Multiple Choice

Which could complete the liquid phase description in the venn diagram?

• Definite shape and low energy particles

• No definite shape and no definite volume

• No definite shape and high energy particles

• No definite shape and medium energy particles

AKS 5B - Gas Laws

Multiple Choice

Tamika inflates and ties off a balloon in her classroom and then takes it outside on a cold, winter day. Immediately, she notices that the balloon has gotten a little bit smaller. Why does this occur?

• because there are fewer molecules in the balloon outside

• because the air pressure is significantly higher when it is colder

• because the molecules in the balloon have slowed down with the temperature

• because the molecules shrink in size when exposed to the colder, outside air

Multiple Choice

How is the pressure of a gas related to its concentration of particles?

• Pressure will expand a gas, enlarging its volume and reducing its density and concentration of particles.

• Pressure will magnify a gas, developing its volume and multiplying its density and concentration of particles.

• Pressure will compress a gas, reducing its volume and giving it a greater density and concentration of particles.

• Pressure will accelerate a gas, extending its volume and allowing a smaller density and concentration of particles.

Multiple Choice

How is the volume of a gas related to its concentration of particles?

• As the volume of a contained gas expands, its pressure concentration of particles will increase.

• As the volume of a contained gas extends, its pressure concentration of particles will increase.

• As the volume of a contained gas decreases, its pressure concentration of particles will increase.

• As the volume of a contained gas compresses, its pressure concentration of particles will decrease.

Multiple Choice

Three balloons are inflated to the same size. The three balloons are submerged in buckets filled with ice water, tap water and water heated to 65°C. What results would you expect from this experiment?

• All the balloons would shrink.

• All the balloons would expand.

• The balloon in the ice water would expand.

• The balloon in the 65°C water would expand.

Multiple Choice

Jayden was given a marshmallow and a syringe in class to experiment with. She placed the marshmallow in the syringe and sealed the end. When she depressed the plunger of the syringe what happened to the marshmallow and why?

• The increased pressure, pushed the molecules closer together, and caused the marshmallow to shrink.

• The decreased pressure, pushed the molecules closer together, and caused the marshmallow to shrink.

• The increased pressure, allowed the molecules to spread apart, and caused the marshmallow to grow larger.

• The decreased pressure, allowed the molecules to spread apart, and caused the marshmallow to grow larger.

Multiple Choice

Relate the temperature of a gas to the kinetic energy of its particles.

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

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

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

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