A 100-W lightbulb is placed in a cylinder equipped with a moveable piston. The lightbulb is turned on for 2.0×10-2 hour, and the assembly expands from an initial volume of 0.90L to a final volume of 5.88L against an external pressure of 1.0 atm.

Use the wattage of the lightbulb and the time it is on to calculate change in internal energy in joules (assume that the cylinder and lightbulb assembly is the system and assume two significant figures).
