A mass of gas at 7oC and 70cm of mercury has a volume of 1200cm3. Determine its volume at 27oC and pressure of 75cm of mercury.
1200cm3
1378cm3
4320cm3
4629cm3
Explicação
\(\frac{V_1P_1}{T_1}\) = \(\frac{V_2P_2}{T_2}\)
\(\frac{70 \times 1200}{7 \times 273}\) = \(\frac{75 \times V_2}{27 + 273}\)
V2 = 1200cm3
\(\frac{70 \times 1200}{7 \times 273}\) = \(\frac{75 \times V_2}{27 + 273}\)
V2 = 1200cm3
