Thermodynamics on new syllabus?

[ibstudent321]

Hi, 

In how much detail do we need to know the pressure-volume graphs and isothermic, isobaric, isochloric and adiabatic processes? All the old past papers have a big question on it in paper 2, but the new specimen paper doesn't. Is this due to a syllabus change or do we still need to know it? 

If so, what exactly do we need to know about the topic? 

Thanks!

@ibstudent321 The new syllabus doesn't have thermodynamics in the core, but only in option B (engineering physics). So unless you are taking option B, you don't have to know anything about this topic. You can download the actual syllabus from the forum's Files & Downloads section: http://www.ibsurvival.com/files/file/3232-physics-syllabus-2016/

You don't need to know adiabatic process but the other three are still there in the syllabus. They're just not named the same. This is what it says in the guide:

•     Sketching and interpreting changes of state of an ideal gas on pressure– volume, pressure–temperature and volume–temperature diagrams 

So clearly, you need to know these 3 graphs and the relationship between each variable.

OK; do we also need to know for example how temperature varies on a pressure-volume graph... etc?

Hey, sorry I just saw this post. Yes, we do need to know all three relationships. They can ask it in either of the paper so make sure you know the graphs as well as the formulas. Good luck!
