Intermolecular Forces Quiz

What indicates a strong intermolecular force?

Liquids with molecules that have strong attraction to each other, tend to have higher boiling point temperatures.

What is the relationship between surface tension and intermolecular forces, and what indicates surface tension?

If the robot sinks, surface tension is low, and if it rests on the surface, surface tension is high. Liquids with strong intermoelcular forces tend to have higher surface tension.

What is the odor and viscosity of water?

Water is colorless and odorless at room temperature, and is a free-flowing liquid that is not viscous.

What is the odor and viscosity of Glycerol?

Glycerol is colorless and odorless at room temperature, and is more viscous than water, and it flows slowly, like honey.

What is the odor and viscosity of Isopropyl alcohol?

It is a colorless liquid at room temperature, and has an odor, and it is free flowing, and is not viscous.

What is the odor and viscosity of hexane?

Hexane is a colorless liquid at room temperature, and has a strong odor, and it is a free-flowing liquid that is not viscous.

What is the boiling point and robot insect observation for water?

Water’s boiling boint is at 100, and the robot floats

Glycerol: 290, robot floats

Isopropyl Alcohol 80 C, robotsinks

Hexane: 69 celcuis, robot sinks

Which liquid has the weakest and strongest intermolecular force?

Hexane has the weakest intermolecular force, as it has the lowest boiling temperature, and it also has a low surface tension, as it struggles to support an object on its surface. Glycerol has the strongest intermolecular force, as it has the highest boiling point, and has a high surface tension, as the robot was able to float (it is able to support the robot).

How does the intermolecular forces in water compare to other substances, and how does the intermolecular forces is isopropyl alcohol compare to the others?

Water has the second strongest intermolecular force, as it has a higher surface tension than Isopropyl alcohol and Hexane, however, it has a weaker intermolecular force compared to Glycerol, as it’s boiling point is lower. Isopropyl Alcohol has the third highest intermolecular force, as it has a higher temperature compared to Hexane, but as a weaker surface tension and boiling point compared to Water and Glycerol.

What explain glycerol’s results in the surface tension experiment?

The robot floated on glycerol because the strong attractions between glycerol molecules made the liquid thick enough to support it.

What is the relationship intermolecular forces and boiling point and surface tension?

A high surface tension and high boiling point indicates strong intermolecular forces between molecules in a liquid.

How might plants be affected if the intermolecular forces in water decreased?

If the intermolecular forces in water decreased, it may result in water being less resistant to evaporation, harming the formation of spherical raindrops and the ability to move upward through plants, resulting in plants not getting enough water to their leaves, photopsynthesis slowing down as leaves dry out, and plants might grow poorly or die.

How does water’s intermolecular forces help plants?

A stronger intermolecular force in water leads to a strong surface tension, as each water molecule has a high force on neighboring molecules. As the molecules on the surface have fewer neighboring molecules, they are held more tightly by the molecules beneath them, and these strong forces allow water to resist evaporation, form spherical raindrops, and move upward through plants.
