Question 1

The property that causes water to have a concave meniscus but mercury to have a convex meniscus is ________.
◦ heat of vaporization
◦ sublimation
◦ surface tension
◦ vapor pressure
◦ critical point

Question 2

The relationship between the vapor pressure of a liquid and temperature can be expressed by the Clausius-Clapeyron equation:

ln[P2/P1] = [ΔvapH/R] × [1/T1 - 1/T2]

Ethanol (C2H5OH) has a normal boiling point of 78.3 °C and, with ΔvapH = 39.3 kJ/mol. What is the vapor pressure of ethanol at 50.0 °C?
◦ 118 Torr
◦ 234 Torr
◦ 354 Torr
◦ 485 Torr
◦ 670 Torr
