6.4. The vapor pressure of ethylene glycol at several temperatures is given below:

T (C) 79.7 105.8 120.0 141.8 178.5 197.3
p* (mmHg) 5.0 20.0 40.0 100.0 400.0 760.0

Use a semilog plot based on the Clausius-Clapeyron equation to derive an equation for p* (mm Hg) as a function of T (C). From the plot, estimate the heat of vaporization of ethylene glycol in kJ/mol.
Clausius-Clapeyron equation: ln p* = -Hv/RT + B

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
