Question

At a constant temperature, the volume of a gas varies inversely as the pressure. A certain gas is in a container with a volume of 7.5 liters at a pressure of 2 atmospheres. If the volume of the gas is reduced to 5.0 liters at the same temperature, what will be the pressure of this gas?

Answer 1

this is chemistry

Answer 2

Mathematics actually

Answer 3

i guess it can be chemistry too

Answer 4

lol im learning this is in chemistry, gas laws unit, too answer this do you know boyles law?

Answer 5

no

Answer 6

P1V1=P2V2

Answer 7

now i do

Answer 8

so you know it?

Answer 9

use this equation you have the initial pressure and volume, and you have final volume.
just remember your answer will be in atm not kPa

Answer 10

but I do know how to convert atm to kPa if your answer has to be in kPa

Answer 11

i got 2.5

Answer 12

not entirely sure

Answer 13

im getting 3 atm

Answer 14

\[P _{1}V _{1}=P _{2}V _{2}\]

P1=7.5 litres
V1=2 atm
V2=5.0 lires

Answer 15

(7.5L)(2atm)=(5.0L)(V2)

Answer 16

do you not get 3?

Answer 17

i guess your right

Answer 18

you seem kind of uncertain... is there something wrong?

Answer 19

nah its 3 Thank you

Answer 20

no problem
