A student is trying to classify an unidentified, solid gray material as a metal or a nonmetal. Which question will best help the student classify the material?
Is the material malleable or ductile?
Does the material feel hard to the touch?
Will the material float in water?
Does the material feel rough or smooth?
Which answer choice correctly describes the ball's kinetic and potential energy?
The ball has more potential energy at position X than at position Z.
The ball has more kinetic energy at position Y than at position W.
The potential energy and kinetic energy of the ball are equal at position X.
The potential energy and kinetic energy of the ball are greatest as position Z.
The student used the diagram to describe changes in the potential and kinetic energy of the water. At which location is the gravitational potential energy of the water the greatest?
Location W
Location X
Location Y
Location Z

Which statement describes the energy changes that occur when water in a tea kettle is heated on a stove that uses natural gas?
Some of the chemical energy in the natural gas transforms into thermal energy, which heats the water. Then some of the thermal energy changes into sound energy when the water forms steam and the steam leaves the kettle.
Some of the thermal energy in the natural gas transforms into sound energy when the water becomes hot. Then some of the sound energy changes into light energy when the kettle becomes warm.
Some of the electrical energy in the natural gas transforms into thermal energy, which causes the water to form steam. Then some of the thermal energy changes into sound energy and light energy when the steam leaves the kettle.
Some of the light energy in the natural gas transforms into chemical energy in the water. Then some of the chemical energy changes into kinetic energy when steam leaves the kettle and into sound energy when the water boils.
When a lion eats a zebra and then uses the energy from the zebra to run, the lion's body converts-
chemical energy to mechanical energy
electrical energy to chemical energy
chemical energy to light energy
mechanical energy to chemical energy
Scientists found this cell and are actively working to identify it. What question will help them determine what kingdom it belongs to?
