第2問 (配点 10) Your school is arranging a work experience programme for students in Years 10 and 11. As a member of the student council, you want to present 11/ some ideas to the school to make the programme a success. You have found a report written by the school council at a school in the UK which looks helpful. Work Experience Week Last month Work Experience Week was held at our school. A11 400 students in Years 10 and 11 were asked to participate. The school provided a list of companies that were willing to accept students for a week, and students were also given the chance to contact companies by themselves. Nevertheless, some of them failed to find a place to work. Students who were not successful in finding a company had to come to school for self- study, so we should find a better way to match up students and companies next year. According to the school, 6% of Year 10 students and 34% of Year 11 students didn't participate. Why was there such a difference? The comments below clearly show the reason for this. Feedback from participants Harry, I really enjoyed the work experience. I found my company from the school's list, so it was easy to set it up. Yu-ming: This was my second time, I'm happy I did it, but most kids in my year just wanted to study for their exams. Maybe it should just be for Year 10. Clara: I couldn't get my first choice, so the workplace was a bit too far. But I think the experience helped me to try harder. Mo: I arranged my own this year. The ones on the list are fine, but several students go to the same place. I wanted to be the only student, and this time I was. Ryan: I already know what I want to be (a physical therapist) and this 2, 3 LIKE 3 To

bについて質問です。 2枚の解答のところに溶媒の体積比をかけているところがあると思うのですが、なぜですか? 問題文には0℃,1.0+10^5Paに換算するとしか書かれていないのに...と思ったのですが、なぜでしょうか?

☆☆ 準 34. 気体の溶解度 3分25℃, 1.0×10 Pa において, 窒素および酸素の水に対する溶解度は,それ ぞれ 1.4×10-2, 2.8×10-2 である。 ここで溶解度は, 水1Lに溶ける気体の体積[L]を0℃, . 1.0×10 Pa に換算した数値である。 これらの気体の溶解に関する次の問い (ab) に答えよ。 ただし, 気体はすべて理想気体とみなすものとする。 a 25 ℃, 5.0×10‘Pa のもとで,窒素を水21) に十分長い時間接触させた。このとき水に溶けてい る窒素の量として最も適当な数値を、次の①~④のうちから一つ選べ。ただし,窒素の量は, 0℃, 1.0×105 Paにおける体積 [L]で表すものとする。 ① 7.0×10-3 ② 1.4×10-2 ③ 2.8×10-2 ④ 5.6×10-2 窒素と酸素の体積比が2:1である混合気体を, 25℃ 1.0×10 Paのもとで,水2Lに十分長い 時間接触させた。このとき水に溶けている窒素と酸素の量を, 0℃, 1.0 × 105 Pa における気体の 体積比で表したとき,最も適当なものを,次の①~⑤のうちから一つ選べ。 A ① 3:1 ② 2:1 ③ 1:1 ④ 1:2 ⑤ 1:3 [2003 追試]
