Talk:A-level Physics/Forces, Fields and Energy/Thermal physics

There's things on latent heat that are supposed to be in the specification, and they're definately in the exam. I must have gotten an outdated specification.--Krackpipe 14:35, 19 January 2006 (UTC)

I've also just crossed out one point that doesnt seem to be in the current spec. --Krackpipe 17:36, 19 January 2006 (UTC)

So there was a question in last Janurary's paper that asked about a suitable method to determine the specific heat capacity of an aluminium block. Decided to add that back in. ---Krackpipe 19:42, 13 June 2006 (UTC)

May be we can add a couple of examples in the page, for instance, conversion between temperature scales, mixing problems, idea gas equation problems, etc. ---Kiwakwok (discuss • contribs) 04:24, 18 June 2014 (UTC)

Specification
From the OCR GCE Physics A specification. Tick with &#10004; when you feel each part of the specification has been covered. Try not to add much more than what is in this list as it would not appear in the exam anyway. Use links to wikipedia for more depth in a topic.


 * 1) Show an awareness that internal energy is determined by the state of the system and can be expressed as the sum of a random distribution of kinetic and potential energies associated with the molecules of the system.  &#10004;
 * 2) Relate a rise in temperature of a body to an increase in internal energy.  &#10004;
 * 3) Demonstrate knowledge that there is an absolute scale of temperature which does not depend upon the physical property of any particular substance, i.e. the thermodynamic scale.  &#10004;
 * 4) Appreciate that, on the thermodynamic (Kelvin) scale, absolute zero is the temperature at which all substances have a minimum internal energy.  &#10004;
 * 5) Show familiarity with temperatures measured in kelvin and degrees Celsius.   &#10004;
 * 6) Define and use specific heat capacity, and show an awareness of the principle of its determination by an electrical method. &#10004;
 * 7) Recall and use ∆Q = mc∆θ. &#10004;
 * 8) Describe melting and boiling in terms of energy input without a change in temperature. &#10004;
 * 9) Recall and use the ideal gas equation pV = nRT, where n is the amount of gas in moles.
 * 10) Appreciate that one mole is 6.02 x 1023 particles and that 6.02 x 1023 mole-1  is the Avogadro constant NA.
 * 11) Recall that the mean kinetic energy of a molecule of an ideal gas is proportional to the thermodynamic temperature.
