Water Flashcards
Name the 6 properties of water
-cohesion
-adhesion
-high specific heat- resistant to change
-high heat of evaporation
-as a liquid, water freezes»»less dense and expands
-water is the universal solvent-it’s a beautiful thing
What is cohesion
Like molecules sticks together
What is adhesion
Unlike molecules stick together
Name the three states that water exists in
Solid, liquid,gas
What did life probably evolved in
Water
Explain the life probably evolving in water
-living cells are 70-90% HOH
3/4 of the earth is covered with HOH
Water exists in all three states (solid liquid, gas)
