metals make good ___________
What are conductors?
100

foam, rubber, cloth all make good ___________

What are insulators?

200
When radiation occurs, thermal energy is transferred by these
What are electromagnetic waves?
200
transfer of thermal energy from one material to another by electromagnetic waves
What is radiation?
200
warming your hands over a fire
What is radiation?
200

material through which thermal energy flows easily

What is a thermal conductor?

200
convection can only occur in these types of materials
What are fluids (liquids and gases)?
300

movement of thermal energy from a warmer object to a cooler object

What is heat transfer?

300
transfer of thermal energy between material by the collisions of particles
What is conduction?
300

Why does a metal spoon feel colder than a wooden spoon even when they are at the same temperature?

 Metals are better conductors of heat than wood. When you touch a metal spoon, it conducts heat away from your hand more efficiently, making it feel colder.

Give an example of convection currents in nature and explain how they work.

An example of convection currents is the rising of warm air and sinking of cool air in a room. This happens because warm air is less dense and rises, while cool air is denser and sinks.

300

radiation is different than other types of thermal energy transfer because it can do this

What is travel through a vacuum (empty space)?

400
average kinetic energy of the particles that make up a material
What is temperature?
400
movement of fluids in a cycle because of convection
What is convection currents?
400

How does insulation help conserve thermal energy in a building?

 Insulation helps conserve thermal energy by reducing the flow of heat between the inside and outside of a building.

400
material through which thermal energy does not flow easily
What is a thermal insulator?
400
if particles in an object are moving slowly, we know this about the temperature
What is it is low or cold?
500
sum of the kinetic energy and the potential energy of the particles that make up a material
What is thermal energy?
500
transfer of thermal energy by the movement of particles from one part of a material to another
What is convection?
500
the force that causes Earth's plates to move, occurs in the mantle
What is convection?
500
the reason cool material sinks and warm rises in a convection current
What is it is more dense?
500

Explain the difference between conduction, convection, and radiation.

  • Conduction is the transfer of heat through direct contact between particles.
  • Convection is the transfer of heat through the movement of fluids (liquids or gases).
  • Radiation is the transfer of heat through electromagnetic waves.
