Answer:
the volume reduces to 6 L
Explanation:
Boyle's law states that the volume of a gas is inversely proportional to the pressure, as long as temperature and other physical conditions are kept constant. This means that, as pressure increases, volum decreases and vice versa.
the formula is: (in blue pen in attached image)
P1 = 3 atm
P2 = 4 atm
V1 = 8 L
V2 = x
making V2 subject of the formula (in red pen in attached image),
V2 = 3*8/4
= 6L
have a great day!!!
