8.2. Thermal Energy Transfer

Here we look into some of the Physics of thermal energy transfer. We start with a bit of recap on the 3 main methods - conduction, convection, radiation. However, the main focus of this chapter is building up a bit of understanding about the reasons behind the greenhouse effect - starting with energy emission from the sun through something called black body radiation, followed by looking at energy absorption of the Earth and the reason why greenhouse gases contribute to global temperature changes.

The section has been divided up as follows:

 

Conduction, Convection, Radiation

We looked at these methods of heat transfer initially at GCSE. Actually, for the IB, it does not go too far beyond the GCSE content you should already be familiar with. 

Conduction is the method of heat transfer due to transfer of thermal energy through molecular collisions. 

Convection only occurs in fluids (i.e. liquids and gases). Warmer regions result in lower densities

A question by question breakdown of the IB papers by year is shown below to allow you to filter questions by topic. Hopefully you have access to many of these papers through your school system. If available, there may be some links to online sources of questions, though please be patient if the links are broken! (DrR: If you do find some broken links, please contact me through the site)

 

Questions on this topic (Section 8) are shown in grey.

Use this grid to practice past IB questions topic by topic. You can see from the colours how similar the question topic breakdown is year by year. The more you can familiarise yourself with the IB question style the better - eventually you will come to spot those tricks and types of questions that reappear each year.
