If [itex]c_v[/itex] is the specific heat at constant volume, authors substitute this into the first law as follows:
[itex]c_v d\theta + pdv = dq[/itex]
How can one deduce that equation for any case? Since the specific heat at constant volume is used, the equation would be valid only where there is no expansion i.e. when dv=0?
