A system contracts from an initial volume of 15.0 L to a final volume of 10.0 L under a constant external pressure of 0.80 atm. What is w? (1 L·atm = 101.3 J) A) -4.0 J B) +4.0 J C) -4.1 ×10² J D) +4.1 ×10² J E) +81 J

Question

Quizplus · Accepted Answer

Work done by the system is given by:w = -P(V2 - V1)w = -0.80 atm (10.0 L - 15.0 L)w = -0.80 atm (-5.0 L)w = +4.0 atm Lw = +4.1 ×10² J
