Do you know how many children there are in the world? I thought there were 3 million Chiidren in the world. In reálity, there are 2.1 billion children in the world. Do you think they all are Iiving sáfely and cómfortably? It is not true. 356,000 children are troubled by póverty. I Knew foreign children were troūbled by póverty, but I didn't know Japanese children were troubled by póverty. 1 in 7 Children in Japanlive in poverty. I was surprised to hear that. Japan is not at war and not a poor country. It is an advanced and developed nation. So, why does it have this problem? There are many causes. First,non-regular employment is increasing. Non-regular employees don't get enough money and they don't have a stable job. Second, the number of elderly people is increasing. When the number of elderly people increases, it burdens Japan's workload. Finally, single-parent families are increasing. So how can we solve these problems? The first is food support. For example, there are certain projects and corporations that carry out food services and children's cafeterias.Certain food services are free for low-income single-parent families. Children's cafeterias' dishes are free or low price for children. There are about 12 children's cafeterias in Koriyama. Second, schooling support. Children can go to supplemental school and go to lessons set up by a support group. There are various ways to solve the problem. What can we do for poor Japanese children?1 think we should understand this present condition and donate money. I want to be a member of a support group. The day when children in Japan and around the world can live safely and with peace of mind Will it come?l hope that children around the world, including Japan, can live safely and securely. Through the SDGS, I hope we can secure happiness for all children.

(2)の3の解き方がわかりません

[図]のように、滑らかに動く軽いピストンを取り付けたシリンダーに、1.0mol の 単原子分子理想気体を閉じ込めて鉛直に立てた。最初、気体の圧力は大気圧 P。 [Pa] と等しく、体積は 1% [m°] であった。 この状態を状態Aとする。状態Aからピストン の固定を解除して、 加熱して体積を 41% [m°] にした。この状態を状態Bとする。 さらに、状態Bから、ピストンを固定し体積を 41% [m°] に保ったまま気体を冷却し、 圧力を Po/4 [Pa] にした。 この状態を状態Cとする。その後、ピストンの固定を解除 し、等温変化てで体積を 1% [m] にした。この状態を状態Dとする。 重力加速度の大き さをg [m/s?]、気体定数を R [J/(mol K)] とする。ピストン、シリンダーは断熱性で、 外部との熱のやり取りはないものとする。 4 大気圧 pP 定経をに Vo W-o 000 [図] Fs W こ (1) 状態Aから状態Bの過程について以下の問いに答えよ。 の気体がした仕事を求めよ。 気体の温度上昇を求めよ。 ③ 気体に与えた熱量を求めよ。 (2) 状態Bから状態Cの過程について以下の問いに答えよ。 の気体がした仕事を求めよ。 ②状態Cでの気体の温度は何Kか。 ③ 内部エネルギーの増加量を求めよ。 も w=pV· 3Vo Po V。 4 4voPo- Bvo 4 ) 状態Aから状態 B、 C、 0へと変化する過程を表すグラフを、 縦軸を圧力、横軸を体積として描け。
