WebCase 2: Work done by the system is positive. Here the first law is written as $$ \mathrm{d}U = \mathrm{d}Q - \mathrm{d}W \,. \tag{2}$$ If work is applied to the system, $\mathrm{d}W$ term becomes negative making two negatives positive, which is identical to equation (1) and heat added to the system is still positive here. http://ch301.cm.utexas.edu/thermo/properties/intro-all.php diverging diamond interchange accidentshttp://ch301.cm.utexas.edu/thermo/properties/intro-all.php cracked phone repair in overland ks
