Enclosed Beneath the Moveable Piston in the Drawing Is 4

Enclosed beneath the moveable piston in the drawing is 4.8 moles of a monatomic ideal gas.The gas performs work on the piston as 2300 J of heat are added from the surroundings.During the process,the temperature of the gas decreases by 45 K.How much work does the gas perform?

A) 5.0 × 10³ J
B) 3.2 × 10³ J
C) 1.4 × 10³ J
D) 6.0 × 10² J
E) 4.4 × 10³ J
