Question 9

most dense to least dense

Answer 9

liquid, solid, gas

Question 10

water is the solvent of life

Answer 10

solvents dissolve solutes creating solutions

Question 11

polarity makes H2O a good what

Answer 11

a good solvent

Question 12

hydrophilic

Answer 12

substances that attract to H2O will be polar

Question 13

hydrophoibc

Answer 13

nonpolar won’t dissolve in H2O

Question 14

High specific heat

Answer 14

amount of energy it takes to heat up 1 gram of a substance by 1 Celsius

Question 15

H2o has a spefiic heat

Answer 15

resists changes in temperature

Question 16

heat of vaporization

Answer 16

energy it takes 1 gra, of water to evaporate, hydrogen bonds must be broken entirely

Question 17

the heat of vaporization creates

Answer 17

evaporative cooling sweating

Question 18

why are these properties important?

Answer 18

all life occurs in water

Question 19

Decsribe CA or NE

Answer 19

City B is the one with the straight line because water helps regulate temperature and City A is the High hill line because it is inland and its not surrounded by water
