Calculate the final temperature of a sample of carbon dioxide of mass 16.0 g that is expanded reversibly and adiabatically from 500 cm3 at 298.15 k to 2.00 dm3. 1) if you want to calculate the work, dw=-pdv -> w = -nrtln(v2/v1). is this expression ok for this problem? if yes, then what t should i use? 1) why the charles law v1/t1=v2/t2 does not hold? if you increase v you do work and so you expect to reduce u and therefore t. but according to charles law, in order to keep the proportion, if you increase v, you also increase t.
