Answer:
At 1.12 atm.
Explanation:
To calculate the pressure (P2), we can use the Gay-Lussac's Law replacing the values of P1 (1.00atm), T1 (100°C=373K) and T2 (143°C=416K):
[tex]\begin{gathered} \frac{P_1}{T_1}=\frac{P_2}{T_2} \\ \frac{1.00atm}{373K}=\frac{P_2}{416K} \\ 0.00268\frac{atm}{K}=\frac{P_2}{416K} \\ 0.00268\frac{atm}{K}*416K=P_2 \\ 1.12atm=P_2 \end{gathered}[/tex]Finally, at 1.12 atm will the temperature reach 143°C.
