Given below are the temperatures at which two different liquids with the same empirical formula have a vapor pressure of 400 torr: Dimethyl ether -37.8oC
Ethanol 63.5oC
Which of the following statements is false?
Increasing the temperature will increase the vapor pressure of both liquids
Intermolecular attractive forces are stronger in ethanol than in dimethyl ether
The normal boiling point of dimethyl ether will be higher than the normal boiling point of ethanol
The reason that the temperature at which the vapor pressure is 400 torr is higher for ethanol than for dimethyl ether is that there is strong hydrogen bonding in ethanol

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.

hope this .

it would only be the stuff in module eight so you need to study all the lessons in that you also could check the flvs

hope this : )
