Heat is:

• The flow of energy from an object that has a higher temperature (warmer) to an object that has a lower energy (cooler)

• The flow of energy from an object that has a lower temperature (cooler) to an object that has a higher energy (warmer)

• None

• The flow of air from an area of higher pressure to an area of lower pressure

The types of heat transfer are:

• Conduction, convection, and radiation

• cold to warm

• Conduction and radiation on only

• Air pressure and stability

Radiation is:

• The transfer of heat from one object to another by electromagnetic waves.

• The transfer of heat from one object to another by contact.

• The transfer of heat from one object to another by friction.

• None

Select all that represent radiation:

• Sunlight is an example

• Electromagnetic Waves

• No direct contact required

• All of the above

What is conduction?

• The transfer of heat by direct contact

• The transfer of heat by electromagnetic waves

• The transfer of heat by convection currents

• None

Which of the following is the best example of heat conduction?

• Standing in the sunshine

• Laying on a cold floor

• Putting your hand above a heater

• Movement of air currents in a room

What is convection?

• The transfer of heat in liquids or gases (fluids) where hot fluids rise while cooler fluids sink

• The transfer of heat by direct contact

• The transfer of heat by electromagnetic waves

• None

A campfire involves:

• Conduction, convection, and radiation

• Only radiation

• Only conduction

• Only convection

Two examples of convection on Earth are:

• The movement of Magma and the movement of air in the atmosphere

• Touching a hot rock

• Sunlight
