Một bình kín chứa 1 mol nitrogen, áp suất khí là 10^5
\(T(K) = t\left( {^\circ C} \right) + 273 = 27 + 273 = 300(K) \Rightarrow \) a) Sai
\(\frac{{pV}}{T} = nR \Rightarrow \frac{{{{10}^5} \cdot V}}{{300}} = 1.8,31 \Rightarrow V \approx 0,0249{m^3} = 24,9l \Rightarrow \) b) Sai
\({W_d} = \frac{3}{2}kT = \frac{3}{2} \cdot 1,38 \cdot {10^{ - 23}} \cdot 300 = 6,21 \cdot {10^{ - 21}}J \Rightarrow \)c) Sai
\(pV = nRT \Rightarrow \frac{{{p^\prime }}}{p} = \frac{{{n^\prime }}}{n} \cdot \frac{{{T^\prime }}}{T} \Rightarrow \frac{{0,25 \cdot {{10}^5}}}{{{{10}^5}}} = \frac{{{n^\prime }}}{1} \cdot \frac{{20 + 273}}{{27 + 273}} \Rightarrow {n^\prime } \approx 0,256\;{\rm{mol}}\)
\(\Delta n = n - {n^\prime } = 1 - 0,256 = 0,744\;{\rm{mol}} \Rightarrow \) d) Sai
