\(\left\{{}\begin{matrix}TT1:\left[{}\begin{matrix}P1=2\left(atm\right)\\T1=27^oC=300^oK\\V1=10\left(l\right)=0,01m^3\end{matrix}\right.\\\\TT2:\left[{}\begin{matrix}P2=5\left(atm\right)\\T2=?\\V2=20\left(l\right)=0,02m^3\end{matrix}\right.\end{matrix}\right.\)
Ta có \(\dfrac{P1}{T1}=\dfrac{P2}{T2}\)
\(\Leftrightarrow T2=\dfrac{P2.T1}{P1}=\dfrac{5.300}{2}=750^oK\)
