The amount of energy required to raise the tempeature of 1kg of a substance by 1K.
Would this be right
Or should I define using the formula? c=E*M*theta
Your definition is correct but it would be better to have a look at sample questions in the past papers to see if it's required to specify any conditions during the measurement of the specific heat capacity. For example, without change of state of the substance, because you might increase the temperature of 1kg a substance at its melting/boiling point and so to increase its temperature by 1K you would need to supply a extra amount of energy.
Also, the definition essentially comes from the formula: c=E/(m*change in temperature)

Definitely look at mark schemes as OCR can be very picky. I think when I was doing G485 last year there would be some papers where different keywords were required on different years for the same question, so I ended up making my own definitions list based purely on the mark schemes.

I see thanks, will do.
So base definitions on most recent exam papers then.

ocr havent asked that, it was an old question that I was basing my answeer for.

The g484 last year was tricky I heard?
I would agree, I found g485 much easier than 484. The first question put me into a bit of a panic then I lost quite a few marks from rushing and not reading the questions properly There was also a definition question in one of the papers which specifically asked you not to use the formula, which completely threw me as I'd only ever learned how to define it using the formula

That newtons 3rd law question for the 1sr question was never asked before. What dwfinition are you talkig about?
The define an electric field caused me to panic, since every year before that they asked to define electric field stewngth.

I have never defined using the formula :P
Hmm I'm not sure I can't really remember the questions... It might have been something to do with gravitational field strength, or I might have just remembered wrongly and it had nothing to do with not using a formula
Have you done June 2015 yet? There was a tricky graphy question on there
Yh just did it this week for my mock. Went horribly for me personally, but i was prepping for f maths mock more so didn't put my 100% into it. Hoping for an a* still, but I'd be content with an A for now. How about you?

Well the G484 may be easier than last year, idk.
Straightforward papers from OCR for a change would be nice

Haha I doubt they will, its the last year, maybe 2nd last year of the old spec papers (our spec). Expect ridiculous questions that test your exam ability more than they test your knowledge of physics..
