Never even knew that existed!! Thanks for that
I'm hoping for an A but I still have electricity to revise but I have the weekend for that so should be grand. Considering the experiments go for so many marks, should hopefully have full marks there provided no sneaky questions are asked like the mocks!
Any tips for getting the A? Is it just knowing definitions, how to the maths stuff and knowing how things work etc? Once you know all that, are you sorted?
There's also few derriviations we have to know0 -

Right, I knew that just forgot to put it in there!
Don't you know for the STS part of the syllabus? Do you need to be able to describe the exact way everything works thats listed in that part of the syllabus? Like for the heat pump, do you need to know how it works? Or for mirages, do you need to know how they're formed? 0 -

I'm not sure about mirages but you have to know how the heat pump works, it has been asked at least once before. And they are fairly strict on the descriptions. For example, in the heat pump question if you didn't mention that the gas takes away LATENT HEAT from the cooler area you'd lose few marks. So if you just said it takes away heat or energy you wouldn't get full marks which I think is a bit harsh cause you're still showing that you know how it works

I'm pretty sure mirages came up before, I'd advise looking at them...0 -

That is harsh... I was checking the syllabus, and it's so confusing, because it says for the STS sections (i.e. where the heat pump is) we only need to know the principle of them, not technical or operational details. It's so confusing regarding what we have to know! 0 -

My teacher says for the STS just read through the summary a number of times so you are familiar with the various terms - no need to learn them in detail like demos and definitions. The exception is the Heat pump that need to be learned in more detail.
Most question on the STS section need one or two word answers.
Derivations (proofs) are also included in the summaries.0 -

This is in the 'measure restistance of a thermistor with temp.' question
Answer?
I think it's because oil is a better conductor of heat and impure water will conduct electricity
