Mr. Ito's students suggested several investigations that could be done to learn about the movement of heat. Mr. Ito completed the investigations in front of his class. The investigations and their results are provided below.
investigation W: A bowl was filled with warm soup. The temperature of the bowl increased.
investigation X: A warm pan was put on top of an ice cube. The ice cube slowly melted.
investigation Y: A marble was placed near a light source. After some time, the marble felt warm.
investigation Z: A cold spoon was put into a warm cup of tea. The spoon quickly began to warm.
Which investigation is an example of the movement of heat through radiation?
Investigation W
Investigation X
Investigation Y
Investigation Z

Why is chemical energy a type of potential energy?
because the energy can be converted to other forms
because the energy is used to power machines
because the energy causes electrons to move
because the energy is stored in chemical bonds
