16
Q

waters unique properties 4

A

universal solvent
high melting and boilling point
high heat capacity
special cohesive and adhisice properties

17
Q

Water is a universal solvent meaning

A

water molecules are polar (diffrent charges at each end) resulting inva weak attraction between molecules known as a hydrogen bond which allows water to dissolve verity of substances

18
Q

water gas high melting and boiling point which means

A

a lot of energy is required ti break hydrogen bonds to change state

19
Q

water melting point

20
Q

water boiling point

21
Q

density in water

A

as it gets colder the water molecules loosen which is opposite of normal substances
when it gets hotter molecules tighten causing higher density

22
Q

water has high heat capacity meaning

A

large amounts of energy required ti increase temperature and large amounts of energy are given off when when water water temperature drops

23
Q

energy from water > heats the

24
Q

energy from pand> given to

A

given ti water to cool the land

25
water has special properties known as
cohesion and adhesion
26
cohesion
attraction of water molecules yo other water molecules
27
adhesion
attraction of water molecules to other substances molecules
28
issues affecting water
fresh water is only 3% not everybody has water increasing temperature of world increases drought and evaporation which decreases plant growth and increases CO2 lvls
29
hydrogen bonding enables water ti dissolve a wide variety of substances
true
30
is liquid water or ice more dense
liquid water
31
water has a ___heat capacity
high
32
metabolic water is generated by
metabolic reactions
