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