Answer 16

partial pressure

Question 17

the ratio of the number of moles of one component to the total number of moles in a mixture

Answer 17

mole fraction

Question 18

to maintain constant P, as V increases T must increase; fewer collisions require harder collisions

Answer 18

charles’ law

Question 19

to maintain constant P and T, as V increases n must increase

Answer 19
