11. An insulated system with two compartments with ideal gas, and a piston is placed in between the two compartments.
Initially, the pressure of the left compartment is greater than the right one, but the piston does not move due to the stoppers.
At some point, the stoppers are removed, so the piston is moving towards right. The entire system is isolated but the piston
itself allows for heat transfer. You can assume the constant volume heat capacity of this ideal gas 2.5 R, where R is gas
constant. You can also ignore the mass and volume of the piston.
68. 根據內政部統計民國 109 年底原住民人口數 57.7 萬人,較 108 年底增加 0.94%; 人口數以 阿美族 21.5 萬人最多、排灣族 10.4 萬人次之、泰雅族 9.3 萬人居第三,三者合計占逾原住 民總人數 7 成。經政府認定的原住民族有 16 族,各縣市原住民人口數,以花蓮縣原住民人 9 萬 3,450 人、占全國原住民人口數 16.20 %最多,臺東縣 7 萬 8,514 人、占 13.61 %次 之,桃園市 7 萬 7,662 人、占 13.46 %居第三,三縣市合計占原住民人口數 4 成 3 ; 各縣市 人口中原住民所占比率,以臺東縣 36.47 %最高,花蓮縣 28.81 %次之,屏東縣 7.44 %居第 三。請試就文中的臺灣原住民族與主要的分布區域的連線配對,在答題卷上作答。
