AKS 5B - Gas Laws

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.

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

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

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

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

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
