Answer 4

P\(\propto\)\(\huge\frac{1}{v}\)

Answer 5

okay thanks.

Answer 6

So u can use
\(\huge\frac{P_1}{P_2}\) = \(\huge\frac{V_2}{V_1}\)

Answer 7

i used that equation...

Answer 8

solved for p_2

Answer 9

my bad i used a different equation

Answer 10

yes, P\(_1\) is given 100 torr, V\(_2\) is given 2*V\(_1\)

Answer 11

Find P\(_2\)

Answer 12

How did you know that you were suppose to use the equation you showed me

Answer 13

From combined gas law i.e PV=nRT

Answer 14

n, R & T are constant so P \(\propto\) \(\huge\frac{1}{v}\)

Answer 15

if volume is doubled then pressure will become half

Answer 16

a linear relationship?

Answer 17

yes

Answer 18

okay thank you

Answer 19

do you want to see my work?

Answer 20

sure
