Q 4(a) [12.5 Marks]
A sample consisting of 2 moles He is expanded isothermally at 0oC
from 5.0 dm3
to 20.0 dm3. Calculate w, q and U for each of the following
situations:
(i) A reversible expansion of the sample;
(ii) An irreversible expansion of the sample against a constant
external
pressure equal to the final pressure of the gas;
(iii) A free expansion (against zero external pressure, i.e., in a
vacuum) of
the sample.
