Question

A gas with a volume of 4.0 is allowed to expand to a volume of 12L. What happened to the pressure in the container if the temperature remains constant

Answer 1

We use old

Boyle's Law

,

P

V

=

k

,

where

k

is a

constan

And the utility of this law means that we could use non-standard units, if our units are consistent.

Given that

P

V

=

k

,

(temperature constant), it follows that...........

P

1

V

1

=

P

2

V

..........

We solve for

P

=
