800cm3

Explanation:

This is a general gas law question

Which has the relationship P1V1/T1 = P2V2/T2

P1 = P1 in kPa

T1 = T1 in K

V1 = 800cm3

V2=?

P2 = 2 * P1

T2 = 2*T1

The volume of gas after the changes (V2), making it as the subject of formula

V2 = P1*V1*T2/P2*T1

V2 = P1 * 800 * 2T1 / 2P1 * T1; dividing accordingly, we have

V2 = 800cm3
