Chris went on a camping trip. During the day it was so hot that he got sunburn. When it was time to go to his campsite, he noticed smoke in the air. His father had started a fire and he felt the heat as he walked by. In the morning while his mother was cooking breakfast he accidentally touched a hot pan and got burned. Although this was the case he still had a lot of fun on the trip.

Identify and explain the different types of heat transfer (convection, conduction, radiation) occurring in the scenario above.

Question 18 options:

Sunburn = radiation;
Smoke rising = convection;
Feeling fire = radiation;
Touching hot pan = convection


Sunburn = radiation;
Smoke rising = conduction;
Feeling fire = radiation;
Touching hot pan = conduction


Sunburn = radiation;
Smoke rising = convection;
Getting warm by a fire = radiation;
Touching hot pan = conduction
