Heat transfer through convection is more efficient in liquids and gases. This is because the particles in these mediums are ________________.

• closer together and move faster

• farther apart and move slower

• closer together and move slower

• farther apart and move faster

The name of heat transfer between two solids which are in direct contact or touching one another is_______

• Conduction

• Convection

• Radiation

• Conservation

Energy can be changed from one form to another.  Changes in the form of energy are called energy conversions.  In an automobile engine, the battery is a form of ____________ energy that is converted to electrical energy.  The electrical energy is then converted to ________________ energy which is also converted to ________________ energy in the motor.

What type of heat transfer is used to toast bread in a toaster and how can you tell?

• It is conduction because the bread gets toasted.

• It is conduction because the bread is touching the toaster.

• It is convection because you put bread in a toaster to toast it.

• It is convection because you can feel the heat a few inches away from the toaster.

Which would be best categorized as heat transfer by conduction?

• A hot air balloon

• Cooling a burn on your hand by running cold water on your hand

• Feeling the heat from a light bulb with your hand when touching the bulb

• Feeling the heat from light bulb while holding your hand 6 inches away from the bulb.
