Intermolecular forces
Intermolecular forces
Forces between molecules
Strength of intermolecular forces in small molecules
Strength of intermolecular forces in small molecules
Weaker
Strength of intermolecular forces in large molecules
Strength of intermolecular forces in large molecules
Stronger
Long vs short hydrocarbons: intermolecular forces
Long vs short hydrocarbons: intermolecular forces
Stronger in long hydrocarbons
Viscosity definition
Viscosity definition
Measure of how easily a liquid flows
How do stronger intermolecular forces affect flow?
How do stronger intermolecular forces affect flow?
Make it harder for liquid to flow
Effect of stronger intermolecular forces on viscosity
Effect of stronger intermolecular forces on viscosity
Increases viscosity (more viscous)
Viscosity of larger hydrocarbons
Viscosity of larger hydrocarbons
More viscous (stronger intermolecular forces)
Syrup vs water viscosity
Syrup vs water viscosity
Syrup is more viscous
Why is syrup more viscous than water?
Why is syrup more viscous than water?
Larger molecules, stronger intermolecular forces
