Question 6

refers to the attraction of molecules for other molecules of a different kind.

Answer 6

adhesion

Question 7

the mass per unit volume of a substance

Answer 7

density

Question 8

is the amount of heat needed to raise the temperature of one gram of a substance by one degree Celsius.

Answer 8

specific heat capacity

Question 9

it also takes an unusual amount of heat to vaporize a given amount of water, because hydrogen bonds must be broken in order for the molecules to fly off as gas.

Answer 9

heat vaporization
