Cohesion – The attraction of water molecules to each other and creates high surface tension in water. An example of how it helps support life on Earth is that it allows insects to walk across the surface.
Adhesion – The attraction of water molecules to other substances and allows water to travel against gravity. An example of this is water moving up a tree even when there is gravity.
Specific heat capacity – the heat required to raise the temperature of the unit mass of a given substance by a given amount. An example of this is a swimming pool staying the same temperature no matter if it is hot or cold outside.
Expansion upon freezing – Water expands when its frozen which will keep it from sinking. Floating ice keeps the water underneath it warm. An example of this is an iceberg floating on top of a body of water.
Universal solvent – Can dissolve almost anything, usually water. An example is that water transports important chemicals or nutrients/minerals that is needed for all living organisms.
I just learned about this lol...
Hope this helps UwU
Answer:
When a saturated solution at a high temperature is cooled, why is the solution separated as a solid? When a saturated solution at a high temperature is cooled, inter molecular space between the molecules of the solution decreases. As a result, no more solute can remain in a solution separating out as a solid crystal.
M(NaCl)=50.0 g
m(H₂O)=150.0 g
m(solution)=m(NaCl)+m(H₂O)
w(NaCl)=100m(NaCl)/m(solution)=100m(NaCl)/{m(NaCl)+m(H₂O)}
w(NaCl)=100*50.0/(50.0+150.0)=25%
