A Closed, Uninsulated System Was Fitted with a Movable Piston $\Delta$

A closed, uninsulated system was fitted with a movable piston. The introduction of 430 J of heat caused the system to expand, doing 238 J of work in the process against a constant pressure of 101 kPa (kilopascals) . What is the value of $\Delta$ E for this process?

A) (430 + 238) joules
B) (430 - 238) joules
C) (238 - 430) joules
D) 430 joules
E) (-238 - 430) joules
