Trạng thái 1: \(\left\{{}\begin{matrix}p_1=2\cdot10^5Pa\\V_1=1000ml\\T_1=???\end{matrix}\right.\)
Trạng thái 2: \(\left\{{}\begin{matrix}p_2=4\cdot10^5Pa\\V_2=200ml\\T_2=0^oC=273K\end{matrix}\right.\)
Quá trình khí lí tưởng:
\(\dfrac{p_1V_1}{T_1}=\dfrac{p_2V_2}{T_2}\Rightarrow\dfrac{2\cdot10^5\cdot1000}{T_1}=\dfrac{4\cdot10^5\cdot200}{273}\)
\(\Rightarrow T_1=682,5K\)
