Which of the following statements is true?

A) w and ΔV have the same sign because the gas expands, work flows into the surroundings

B) w and ΔV have the opposite sign because the gas expands, work flows into the surroundings

C) w and ΔV have the same sign because the gas expands, work flows out of the surroundings

D) w and ΔV have the opposite sign because the gas expands, work flows out of the surroundings
