Question

The pressure of a gas p(v) varies inversely with the volume of the gas v. The pressure of a gas measures 25 kg/cm2 when its volume is 200 cm3.

Which equation can be used to find the pressure of the gas when the volume is changed?

Answer 1

p(v)=8/v
p(v)=8v
p(v)=5000/v
p(v)=5000v

Answer 2

Please help me :(

Answer 3

pv = nrt?

Answer 4

if presure increase, then volume has to decrease

Answer 5

I dont know how I'd find it..

Answer 6

Would it be the first one?

Answer 7

or the 3rd one?

Answer 9

*sorry, i'm taking so long, im getting spread pretty thin between everyone ^_^

Answer 10

its okay!

Answer 11

if P(v) = 25, and v=200, which equation is true?

p(v)=8/v
p(v)=8v
p(v)=5000/v
p(v)=5000v

check:
p(v)=8/v
25 = 8/200 [FALSE]

check the rest of the choices like i just checked the first one

Answer 12

u get the answer?

Answer 13

I think. D?...

Answer 14

D or C? @DemolisionWolf

Answer 15

p(v)=5000/v
25 = 5000/200 [TRUE]

p(v)=5000v
25 = 5000(200) [FALSE]

Answer 16

have a nice night ^_^
