【至急】この文章の題名として最も適切なものは何かという問いです。私は、②だと思ったのですが、解答は①です。 よろしくお願い致します。

次の英文を読んで、 問 1 ~ 問8に答えなさい。 (配点50点) Inspired by fierce family battles for the last remaining piece of cake, a team of three high schoolers in southwestern Japan's Oita *Prefecture have invented a device that cuts round cake and pizza evenly, no matter how many pieces are sliced, and their creation won the top prize in the prefecture's invention contest in 2021. The three students are members of the industrial technology club at Oita Prefectural Kunisaki High School. Their clever invention to solve a daily life problem with a flexible *2mindset won the governor's award in the competition and is gathering attention. Twelve students in the electronics department of the school ( 1 ) to the industrial technology club, which has continued to submit works to the invention contest for about 40 years. Five of their creations won prizes in the high school division of the 2021 edition of the competition that was launched in 1941. The top prize-winning device, whose name translates to "Let's kindly divide it up," was invented by second-year students Wataru Onoda, 16, Rinto Kimura, 17, and third-year student Mitsumi Zaizen, 18. It was inspired by bbattles for birthday cake in Onoda’s family. He needed to defeat his rival two sisters in games of rock-paper-scissors to get the last remaining piece because the cake was always cut into eight pieces despite his family having seven members. Based on Onoda's idea to equally divide a cake into seven pieces, Kimura created a drawing and computer program to precisely make parts for the device. While Zaizen could not be involved in the actual production due to preparations for her university entrance she created a video for the presentation, using her experience of winning a prize in the competition for two years in a row. exams, (2 ) a two-month trial and error process, the device was completed. When a cake or pizza is placed on a turntable made with a laser beam machine, it can be cut evenly into

(2)について 窒素だけの状態方程式を立てるときに、混合気体の体積を使える理由がわかりません💦赤い四角で囲ってあるところもどういう意味なのかわからないので教えて頂きたいです🙇🏻‍♀️

56 (1) 40°C (2) 6.0L (3) 24L 解説 (1) ヘキサンと窒素はそれぞれ 0.20mol ずつなので, ヘキサン の分圧は,分圧=全圧×モル分率より, *3 1.0×105x- 0.20 0.20 +0.20 -=5.0×10^(Pa) ヘキサンの飽和蒸気圧が,この分圧よりも小さくなる温度では, 一 部が液体となる。 よって, 蒸気圧曲線より 40℃。 (2) 17℃のとき, ヘキサンは気体と液体が共存するので,その分圧は 飽和蒸気圧に等しく, 蒸気圧曲線より 2.0×10'Pa である。 このとき, 窒素の分圧DN2 は, PN2=1.0×105-2.0×10=8.0×104 (Pa) 混合気体の体積を V1 〔L〕 とすると, 窒素だけについての状態方程 式PN2VI = NRT より, *6◄ 8.0×10×V=0.20×8.3×10®×(17+273) V1≒6.0 (L) (3) 体積を膨張させてヘキサンがすべて気体になったとき, ヘキサン の分圧は17℃ での飽和蒸気圧 2.0×10Pa に等しい。 全体の体積 をV2〔L〕 とすると, ヘキサンだけについての状態方程式 Phex V2 = nhex RT より, 2.0×10 x V2=0.20×8.3×10×(17+273) V2≒24(L) モル分率=- 1*4 気液平衡のときのヘキサンは, 体積に関係なく飽和蒸気圧を 示す。 ヘキサンと窒素の分圧の変化 を示すと, (×105 Pa)↑ 1.0 圧力 その物質の物質量 全物質量 0.8 0.5 N₂2 ヘキサン 0.2 0 17 40 60(°C) TAB 1⑥ ここでの体積V」 は,窒素分 子の動ける範囲であると同時 に、混合気体の動ける範囲で もある。 つまり, V1 が求め る体積である。
