Question

Can anyone help me with the following question please? Thanks in advance!

Answer 1

(a) p = 0.8 atm

(b) V = 1 L

(c) `pV = 2.5 × 2 = 5.0 atm L`

(d) `pV = 2 × 2.5 = 5.0 atmL`

Explanation:

(a) Read off pressure from x-axis at volume of 5L:

p = 0.8 atm

(b) Read off volume from y-axis at pressure of 5 atm:

V = 1 L

(c) Read off pressure from graph at volume of 2 L (from question) then use Boyle's Law, `pV =`constant:

p = 2.5 atm
`⇒ pV = 2.5 × 2 = 5.0 atm L`

(d) I've assumed there was a typo in the question and that it should read "a pressure of 2 atm". Read off volume from graph at pressure of 2 atm (from question) then use Boyle's Law, `pV =`constant:

V = 2.5 L
`⇒ pV = 2 × 2.5 = 5.0 atmL`
