How does hydrogen bonding contribute to the unique properties of water?
Hydrogen bonding makes water less polar
Hydrogen bonding creates repulsion between water molecules
Hydrogen bonding creates cohesion, surface tension, and the ability to absorb heat.
Hydrogen bonding decreases the boiling point of water
Give two examples of everyday life applications of surface tension.
Pouring water into a glass
Blowing bubbles with a bubble wand
1. Water striders walking on the surface of water. 2. Formation of droplets on a leaf after rain.
Boiling water in a pot
What factors affect the surface tension of a liquid?
Volume, viscosity, and pH level
Color, pressure, and density

Time, weight, and shape
What happens to the surface tension of a liquid as the temperature increases?
It increases with temperature
It decreases with temperature
It remains constant with temperature
It depends on the type of liquid
