Energy and Electricity Test REVIEW

A metal pan is sitting on the stove. As the pan heats up, the handle starts to get hot as well. This is an example of -

• Expansion

• Radiation

• Convection

• Conduction

Students want to investigate how heat energy can move. The setup of their investigation is shown in the picture.

• Both ice cubes started out the same size.

• Ice cube 1 melts faster than ice cube 2.

• When the ice cubes melt, they turn to liquid.

• The bars are made of the same kind of metal

• the bulb reflects sunlight until it shines brightly and makes heat energy.

• the physical properties of the battery are changed by the chemicals inside it.

• the wires that connect the parts stop heat energy from flowing.
