This happens because the cohesive water is attracted to itself which is why the water beads up on the hood. Water cohesion is most noticeable when it has a sticky quality. For example when something gets wet the cohesive water tries to stick together.

This allows insects to walk, mate and feed on top of water. The cohesive property is also responsible for plant's’ ability to pull water upward from the roots to the leaves.

This relates to Chemistry because you look at whether the positive or negative charges of Oxygen and Hydrogen atoms make up the water molecules.

  • The pressure of the top of a liquid that is caused by coming together of particles on the top layer by the big amount of the liquid, which causes it to make the amount of surface area less.

  • Bugs walking on water. Bugs can walk on water because they don’t have a lot of weight so they don’t puncture holes in water like we do when we go in the water because we have much more weight.
  • Washing with cold water vs. hot water. We wash dishes, hands or our bodies with hot water and it's because the surface tension is lower so it gets things wet better than cold water.

If there was no such thing as surface tension then the smallest things on Earth would sink to the bottom of water. For example, instead of the particles from dust sticking to the top of the water it would all sink to the bottom and kill all of the plants and animals. This would then result the ecosystem to start falling apart.]]> 2017-04-25 23:08:10 UTC https://padlet.com/64645/aoe7szboa3bh/wish/168249760 Relation to chemistry: 64645 https://padlet.com/64645/aoe7szboa3bh/wish/168249823
  • Surface tension is when negative and positive particles come together really tightly in water and create this dip so that light items don’t sink. This relates to chemistry because we had to deal with polar and non-polar things and decide whether they were non-polar or polar.
