What is kinetic energy?

• The energy of an object due to its position.

• The energy of an object because of motion.

• The energy stored in chemical bonds.

• The energy of an object due to its temperature.

Why does the bigger pot have more energy overall, even though both pots have the same temperature?

• Because it contains more water or mass

• Because it is made of metal

• Because it is closer to the heat source

• Because it is a different color

Match the following

• insulator

• a material through which thermal energy does not flow easily

• convection

• the transfer of thermal energy between materials by the collisions of particles; direct contact

•  radiation 

• a material through which thermal energy flows easily

• conductor

How do particles behave during conduction when they are heated?

• They move slower and spread apart.

• They move faster and bump into one another.

• They stop moving completely.

• They move in a circular pattern.

What is convection?

• The transfer of heat in a solid through direct contact.

• The transfer of heat in a fluid caused by the movement of hotter, less dense fluids rising and cooler, more dense fluids sinking.

• The transfer of heat through electromagnetic waves.

• The transfer of heat in a vacuum.
