Six liters of gas is 1.5 atm. What pressure is obtained when the volume is 12 L?

Sagot :

Answer:

This is what we're given:

V

1

, or initial volume, which is

2.5 L

.

P

1

, or initial pressure, which is

1.5 atm

.

P

2

, or final pressure, which is

1 atm

.

We have to find

V

2

, or the final volume.

Boyle's law actually relates all four of these variables!:

P

1

V

1

=

P

2

V

2

This equation can be rearranged to have only

V

2

on one side:

V

2

=

P

1

V

1

P

2

Now, we just need to plug in all of the variables to find

V

2

:

V

2

=

1.5 atm × 2.5 L

1 atm

V

2

=

1.5

atm

×

2.5 L

1

atm

V

2

=

3.75 L
