1) If the pressure on 2.6 liters of a gas at 860 Torr is increased to 1000 Torr,

2.24 liters is the volume of the gas if pressure is increased to 1000 Torr.

Explanation:

Data given:

Initial volume of the gas V1 = 2.6 liters

Initial pressure of the gas P1 = 860 Torr 1.13 atm

final pressure on the gas P2 = 1000 Torr 1.315 atm

final volume of the gas after pressure change V2 = ?

From the data given above, the law used is:

Boyles Law equation:

P1V1 = P2V2

V2 = P1V1/P2

= 1.13 X 2.6 / 1.31

= 2.24 Liters

If the pressure is increased to 1000 Torr or 1.315 atm the volume changes to 2.24 liters. Initially the volume was 2.6 litres and the pressure was 860 torr.
