Conduction, Convection and Radiation

Question 1

Which part of the human body loses the most heat?

Answer 1

The human head loses the most heat.

Question 2

What method of heat transfer occurs when particles with a lot of energy take the place of those with less?

Answer 2

Convection occurs when particles with a lot of energy take the place of those with less.

Question 3

Which of these methods of heat transfer does not involve particles?

Answer 3

Radiation is energy transferred as waves and does not involve particles. Conduction does involve particles.

Question 4

What method of heat transfer occurs mainly in solids?

Answer 4

Conduction occurs mainly in solids. Radiation can occur in a vacuum.

Question 5

Which states of matter are fluids?

Answer 5

Gases are fluids for they ‘flow’. But liquids flow as well and so are also fluids.

Question 6

What method of heat transfer do we see in our weather patterns?

Answer 6

We see convection currents (and so heat transfer by convection) in our weather patterns. Conduction does not affect our weather.
