what is interfacial tension in liqui liquid extraction?
Answer:
3.31 atm.
Explanation:
- Gay-Lussac's law states that for a given mass and constant volume of an ideal gas, the pressure exerted on the sides of its container is directly proportional to its absolute temperature.
∵ P α T.
<em>∴ P₁T₂ = P₂T₁.</em>
P₁ = 3.00 atm, T₁ = 20.0 °C + 273.15 = 293.15 K.
P₂ = ??? atm, T₂ = 50.0 °C + 273.15 = 323.15 K.
<em>∴ P₂ = (P₁T₂)/T₁</em> = (3.00 atm)( 323.15 K)/(293.15 K) = <em>3.307 atm ≅ 3.31 atm.</em>
