How does the speed of light in water compare to its speed in air? (7.P.10.3)

• The speed is faster in water than in air because the molecules are closer together.

• The speed is slower in water than in air because the molecules are closer together.

• The speed is the same in water because it is constant in all mediums.

• The speed cannot be compared without knowing the temperature.

Alexander hooks a rubber band around his thumb and forefinger. He moves his fingers apart, stretching the rubber band. With a quick, sudden motion, he bends his thumb forward so that the rubber band slips off. What happens next? (7.P.11.2)

• The potential energy stored in the rubber band changes to heat energy.

• The potential energy stored in the stretched rubber band changes to kinetic energy.

• The potential energy stored in Alexander’s body changes to kinetic energy.

• The potential energy stored in Alexander’s body changes to potential energy in the rubber band.

Which statement best explains why a bouncing basketball will not remain in motion forever? (7.P.11.3)

• The energy is transferred to heat and chemical energy as it hits the ground.

• The energy is transferred to light and potential energy as it hits the ground.

• The energy is used up and destroyed as it hits the ground.

• The energy is transferred to sound and heat energy as friction as it hits the ground.

Which of the following statements cites evidence about the behavior of energy in the image below? (7.P.11.3)

• Chemical energy from the battery is transferred into electrical energy and then changed into light energy and then is transferred back into the battery to restore chemical energy.

• Electrical energy is created from the chemical energy of the battery and is then changed into sound energy.

• Chemical energy from the battery is transferred into electrical energy until the energy is destroyed and the battery stops working.

• Chemical energy from the battery is transferred into electrical energy and then changed into light energy.

Krystal puts a hot spoon into a bowl of cold ice cream. Based on your knowledge of heat flow, what will be the result? (7.P.11.4)

• The ice cream will melt because the cold will flow from the ice cream to the spoon.

• The spoon will become colder because the cold will flow from the ice cream to the spoon.

• The ice cream will melt because heat will flow from the spoon to the ice cream.

• The ice cream will not be affected.
