\(TT1\left\{{}\begin{matrix}T_1\\p_1\\V_1\end{matrix}\right.\)
\(TT2\left\{{}\begin{matrix}V_2=V_1-\frac{V_1}{5}=\frac{4}{5}V_1\\T_2=T_1-30\\p_2=p_1+\frac{p_1}{10}=\frac{11}{10}p_1\end{matrix}\right.\)
phương trình trạng thái
\(\frac{p_1.V_1}{T_1}=\frac{p_2.V_2}{T_2}\)
\(\Leftrightarrow\frac{p_1.V_1}{T_1}=\frac{\frac{11}{10}p_1.\frac{4}{5}.V_1}{T_1-30}\)
\(\Rightarrow T_1=250K\)
