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.

Store When you stop thinking about the new information, your brain moves it from your short-term memory into your long-term memory*. It breaks the information into smaller parts. It stores the information in different areas of your brain. For example, when you learn a new word in English, you learn its spelling pronunciation, and meaning. This information is stored in different areas of your brain. 6 Do you ever see a word and sav. "I know it. but I can't say it!” That's because you can find some of the information, but you can't find all of it. You remember something about the word, but not enough to put it together. When you truly.remember the word, you connect all its. different parts.;Every time you think about the word, those connections get stronger. With every repetition, you can find the information faster. Repetition is the secret to good memory, but it does not mean repeating the same thing, the same way every time. If you practice your learning in different ways, your brain connections get stronger. For example, when you hear the word, you connect one way. When 7 8 you write the word, you connéct a different way. Each time you add new connections to the word, you make the memory stronger. Repetition and practice are the keys to remembering what you learn. 3 long-term memory: the type of memory that stores information for a long period of time

THE SECRET TO GOOD MEMORY There is a saying in English, "In one ear and out the other." It means we hear something, and we forget it quickly. Is it true? 1 In 1895, a doctor(named Hermann Ebbinghaus)researched the question, “How quickly do people forget new information?" He found that people forget new information very quickly] Within an hour, a person forgets about 55%. Within 24 hours, a person forgets about 70%. 2 人はとれたた We do not forget all information that quickly. If you(burn, yourself on a kitchen stove, you will remember to be careful for á long time. That's because you were in danger. In the classroom, you are not in danger. In the classroom, it is easy to forget your learning. 3 How can you remember more?_You need to fepeat what you learned many timesARepetition is the secret. Language teachers say it takes at least 20 different repetitions to learn a word in a different language! This does not mean 20 repetitions in one hour. Learning requires repetition over days, weeks, and months.. 4 Why not 20 repetitions in an hour? When you repeat the same information again and again, the information stays in your short-term memory?. The information is easy to find, but it does not stay in short-term memory for long. 5 1curve: a line in a graph 2 short-term memory: the type of memory that stores information temporarily, e.g., while repeating a phone number
