Which statement does BEST describe the energy of the objects in the drawing?
The pool of water has more kinetic energy and the falling water has more potential energy.
The falling water has potential energy and the rock over which it flows has kinetic energy.
The water has potential energy at the top of the waterfall and increasing kinetic energy as it falls.
The water at the top of the fall has kinetic energy that becomes potential energy as it falls into the pool.
Which statement does BEST describe what occurred during this investigation?
A new property was acquired when the nail became magnetized and caused a chemical change in the nail.
When the nail became magnetized the iron atoms in the nail were temporarily aligned and caused a physical change.
The electric current passing through the wires heated the nail and caused the nail to undergo a chemical change.
The electric current passing through nail temporarily changed the iron atoms into another substance and caused a physical change.

A carpenter rubs sandpaper on a wooden bench to make the bench smoother. The sandpaper will get warm as it is rubbed on the bench. As a result of the friction between the sandpaper and the bench, thermal energy is converted to
chemical energy that is stored by the sandpaper.
radiant energy that is transferred to the bench.
the potential energy that is stored by the wood.
the heat energy that is transferred to the air.
Hot objects begin to cool as
cooler air is transferred to the object.
energy in the object is transferred to the surrounding air.
atoms in the object react with the oxygen in the air.
energy in the object cancels out energy in the air.
Laura bruised her knee. She applied an ice pack to the bruised area. When she removed the ice pack from the injured knee, she noticed that the temperature of her skin was lower than the rest of her body. What is the MOST likely reason this occurred?
increased blood flow due to the ice pack caused the skin to be cooler.
The cooling energy of the ice pack was transferred to the skin.
Heat energy from the skin was transferred to the ice pack.
The air surrounding the ice pack cooled the skin.
Which is the MOST likely way an energy-efficient window reduces thermal energy transfer?
It decreases the likelihood of condensation on the window.
It allows the window to reflect more sunlight.
It absorbs and traps heat from sunlight.
It acts as an insulator.
