Trả lời:

Giải bởi Vietjack

Đáp án đúng là C

Phương pháp giải

Xét bóng ở hai trạng thái: trạng thái bình thường và trạng thái bóng nổ.

Sử dụng phương trình trạng thái khí lí tưởng: $\frac{p_{1} V_{1}}{T_{1}} = \frac{p_{2} V_{2}}{T_{2}}$

Lời giải

Trạng thái 1: $\{\begin{cases} p_{1} = 105000 Pa \\ V_{1} = 15, 8 m^{3} \\ t_{1} = 27^{0} C \Rightarrow T_{1} = 27 + 273 = 300 K \end{cases}$

Trạng thái 2 – khi bóng nổ: $\{\begin{cases} p_{2} = 27640 Pa \\ V = 39, 5 m^{3} \\ T_{2} \end{cases}$

Áp dụng phương trình trạng thái: $\frac{p_{1} V_{1}}{T_{1}} = \frac{p_{2} V_{2}}{T_{2}} \Leftrightarrow T_{2} = \frac{p_{2} V_{2} T_{1}}{p_{1} V_{1}} = \frac{27640 .39, 5 .300}{105000 .15, 8} = 197, 43 K \Leftrightarrow - 75, 57^{0} C$
