熱力学について質問です。 問題文の一定の外圧1.00atmをどう扱ったら良いかよく分かりません。自分でとりあえず解いてみたんですが合ってる自信あまりないです。もし分かる方いらっしゃいましたら、ご教授していただけませんか?🙇‍♂️

Problem 2 A sample consisting of 1.00 mol of perfect gas molecules at 300 K is expanded isothermally from initial pressure of 3.00 atm of a final pressure of 1.00 atm against a constant external pressure of 1.00 atm. Determine the values of q, w, AU, AH, AS, ASsur, and AStotal. 300Kにある完全気体 1.00mol の試料が、 温度一定で始めの圧力 3.00 atm から終わりの圧 カ 1.00 atm まで、一定の外圧 1.00 atm に抗して、 膨張する。 この過程に対して、9, w, AU,AH, AS, AS r, ASiosal を求めよ。 管品可運勝張より、Tが喫化しないためるリ=D 始めの体様をV終わりの体殊をソュとおくと.
