Unformatted text preview: Work and the First Law Expansion/compression work is called ”prork”and in this
context the First Law becomes dU = dq + dw = dq - pdV Constant volume conditions (Heat and the First Law) dU : dqy ( qu : dq at constant V) and dV: 0
so AU: U2 - U1: qV. The heat withdrawn from the surroundings by a constant-volume
system is equal to the change of internal energy of the system. ...
