Trạng thái 1: \(\left\{ \begin{array}{l}{V_1} = 2\ell \\{p_1} = 1,5atm\\{T_1} = 27 + 273 = 300K\end{array} \right.\)

Trạng thái 2: \(\left\{ \begin{array}{l}{V_2} = 0,3\ell \\{p_2} = 1,8atm\\{T_2} = ?\end{array} \right.\)

Áp dụng: \(\frac{{{p_1}{V_1}}}{}.\frac{{{p_2}{V_2}}}{} \Rightarrow {T_2} = \frac{{{p_2}{V_2}{T_1}}}{{{p_1}{V_1}}} = \frac{{18.0,3.300}}{{1,5.2}} = 540K\)

Mà \({T_2} = 273 + {t_2} \Rightarrow {t_2} = {267^0}C\)
