Glycerol boils at a higher temperature than water. what does this indicate about the attractive forces of glycerol? they are nonexistent. they are the same as those in water. they are stronger than those in water. they are weaker than those in water.

They are stronger than those in water.

Explanation:

The attractive forces in the substances are responsible for the molecules to be together. If we want to boil a substance, we need to break these forces, so the molecules can be separated in the gas phase. As stronger is the force, as difficult is to break it, and more energy is necessary to do it, so the boiling temperature is higher.

Option C on EDGE C:

Explanation:

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
