Consider each of the following processes and determine if work is done by the system, work is done on the system or no work is done. N2 (g) → N2 (l) 2 Na (s) + 3 H2O (l) → 2 NaOH (aq)+ H2 (g) 2 NO (g) + O2 (g) → 2 NO2 (g) 2 CH3OH (l) + 3 O2 (g) → 2 CO2 (g) + 4 H2O (g) 4 NH3 (g) + 5 O2 (g) → 4 NO (g)+ 6 H2O (g)

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
