water Flashcards
1
Q
what are the unique properties of water?
A
adhesion/surface tension, cohesion, high specific heat, high polarity, lower density as a solid
2
Q
why does adhesion/surface tension occur?
A
water molecules form hydrogen bonds with
other polar molecules
3
Q
why does cohesion occur?
A
water molecules form hydrogen bonds with
each other
4
Q
why does high specific heat occur?
A
hydrogen bonding causes water to absorb large
amounts of thermal energy as its temperature
increases
5
Q
why does high polarity occur?
A
the bent/unsymetrical shape
6
Q
why does low density occur?
A
lattice structure keeps the water molecules spread apart
