Question

The volume of a gas V held at a constant temperature in a closed container varies inversely with its pressure P. If the volume of a gas is 1000 cubic centimeters when the pressure is 450 mm Hg, find the volume when the pressure is 250 mm Hg.

Answer 1

555.56

Answer 2

given that V varies inversely with pressure
V= kP

given V (1000) and P (45) find k (constant of proportionality)
V=kP
k=V/P
=1000/450
k=2.222....

find V if the pressure is 250

V= 2.222(250)
v=555.555...

Answer 3

or approximately 555.56

Answer 4

thats what I thought! thank you!!

Answer 5

glad to help. .

Answer 6

medalssss :-)

Answer 7

somehow its 1800? not 555.56

Answer 8

its 1000*450 / 250
