Question

1. as mentioned throughout the video, hydrogen bonds are responsible for many of waters properties. select one of the above properties and explain how hydrogen bonds contribute to the property. (bonus points)

Explanation:

Hydrogen bonds in water occur between the hydrogen of one water - molecule and the oxygen of another. They contribute to properties like high surface tension (the hydrogen bonds create a 'skin' on the water surface, allowing small insects to walk on water), high specific heat (a large amount of energy is needed to break the hydrogen bonds and raise the temperature of water), and cohesion (water molecules stick to each other due to hydrogen bonds). For example, in the case of high surface tension, the hydrogen - bonded network resists external forces, creating a tension at the surface.

Answer:

Hydrogen bonds contribute to water's high surface tension. The hydrogen - bonded network of water molecules creates a cohesive force at the surface, allowing phenomena like insects walking on water.
