25 x 26 x 27 x 28 x 8 = 3 931 200 

\(6,24-\left(30+x\right)=x-\left(28-10\right)\\ \Leftrightarrow24-30-x=x-18\\ \Leftrightarrow-6-x=x-18\\ \Leftrightarrow x-18+x+6=0\\ \Leftrightarrow2x-12=0\\ \Leftrightarrow2x=12\\ \Leftrightarrow x=6\)

6: \(\Leftrightarrow-6-x=x-18\)

\(\Leftrightarrow-2x=-12\)

hay x=6

6, <=> 24-30-x =x -28+10

<=> -6-x = x -18

<=> x= 6

Phương trình trạng thái khí lí tưởng:

\(\dfrac{p_1\cdot V_1}{T_1}=\dfrac{p_2\cdot V_2}{T_2}\)

\(\Rightarrow\dfrac{4\cdot6}{293}=\dfrac{p_2\cdot4}{313}\)

\(\Rightarrow p_2=6,41atm\)
