Chemistry- Water by Brandon Edwards https://padlet.com/66910/k82qzr17891g en-us 2017-04-19 13:06:25 UTC 2025-10-22 14:20:28 UTC hello@padlet.com Adhesion 66910 https://padlet.com/66910/k82qzr17891g/wish/166998688
  • Adhesion: The “stickiness” molecules have for other molecules
  • Real world application: Paint sticking to the wall
  • Human Impact: Water molecules adhering to hemoglobin in blood
  • Relationship to chemistry: Molecules “Clinging” to each other
  • Relationship to water cycle:  Accumulation, Precipitation, Transpiration

    Real world application - walking on water, the density of a human is more than the water
    Human and/or global impact - global~shape of droplets of water are formed by gravity which is a global impact…..human~ Surface tension of body fluids correlates directly to the development of pathological states.
    Relationship to chemistry- Surface tension is the energy, or work, required to increase the surface area of a liquid due to intermolecular forces.
    Relationship to water cycle- evaporation only happens at the surface of the liquid because the top layer of water only has the water molecules under it and none above to attach to. Where as under the first layer they have different molecules all around of them.

Talk about what accumulation, precipitation, and transpiration are. ]]> 2017-05-01 13:39:07 UTC https://padlet.com/66910/k82qzr17891g/wish/169164219 Comment 54880 https://padlet.com/66910/k82qzr17891g/wish/169305953 I would try and explain how it relates to chemistry more.]]> 2017-05-01 23:54:21 UTC https://padlet.com/66910/k82qzr17891g/wish/169305953 60567 https://padlet.com/66910/k82qzr17891g/wish/170653219 2017-05-09 01:47:42 UTC https://padlet.com/66910/k82qzr17891g/wish/170653219 60567 https://padlet.com/66910/k82qzr17891g/wish/170653222 2017-05-09 01:47:43 UTC https://padlet.com/66910/k82qzr17891g/wish/170653222
