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.

Smouldering propagates in a creeping fashion, around 0.1 mm/s (0.0039 in/s), which is about ten times slower than flames spread over a solid.
WebSOLUTION. The heat of solution per molecule of solute is given by q = ∂ W /∂ n — w ′ 0, where W is the heat function of the solution and w ′ 0 the heat function per particle of the pure solute. Since w ′ 0 is not affected by the phase transition in solution, we have for the discontinuity of q.
