gases part 2

Question 1

what does pressure is gases correspond to

Answer 1

the force they exert on a surface

Question 2

what happen when the kinetic energy is greater

Answer 2

faster the partciles move, more collisions with each other and the walls of their container

Question 3

how is gas pressure shown in a u-tube manomater

Answer 3

the height of a column on liquid, which is usually mercury

Question 4

in a close u-tube, how do u fine pressure exerted by the gas

Answer 4

difference of height in mmhg between the two columns of mercury

Question 5

what is different in an open u-tube

Answer 5

you have to consider atmospheric pressure

Question 6

what do you in open when gas pressure is greater,

Answer 6

find the difference in height and add it to the atmospheric pressure

Question 7

what do you do in an open when gas pressure is less

Answer 7

find difference in height than subtract from atmospheric pressure

Question 8

how many mmhg is 101.3 kpa

Answer 8

760mmhg

Question 9

at a constant temp and number of moles, what is the relationship between volume and pressure

Answer 9

volume is inversely proportional to the pressure of the gas

Question 10

what is formula for boyles law

Answer 10

p1v1 = p2v2
