http://www.ecourses.ou.edu/cgi-bin/ebook.cgi?topic=th&chap_sec=04.1&page=theory WebAlternatively you could reason using the formula: d U = d Q − d W (using your notation conventions, were U is internal energy, W is work and Q is heat added to the system) d W = P d V. Therefore. d U = d Q − P d V. Therefore if d V (change in volume) is positive, d U (change in internal energy) is negative. Share.
