Question

A sample of gas has a pressure of 1.5 atm and a volume of 3.5 L, what would be the pressure of this sample of gas if the volume decreases to 2.8 L? Show all of the work used to solve this problem

Answer 1

Assuming constant temperature, you can use Boyle's Law
\[P_1V_1=P_2V_2\]

Answer 2

what does that mean? @peachpi

Answer 3

It means the product of the pressure and volume don't change. You know the pressure and volume at the beginning. They are P1 and V1.

You know the volume after the decrease. That's V2.
Solve for P2

Answer 4

can you set up the equation?

Answer 5

@peachpi

Answer 6

(1.5 atm)(3.5 L) = \(P_2\)(2.8 L)

Answer 7

is the answer 1.875?

Answer 8

yes

Answer 9

what unit?

Answer 10

what's the unit for pressure given in the question?

Answer 11

atm?

Answer 12

yes
