A container of gas has a volume of 3.5 L and a pressure of 0.8 atm. Assuming the temperature remains constant, what volume of ga
strojnjashka [21]

Answer:

The correct answer is option A.

Explanation:

Initial volume of the gas =V_1=3.5 L

Final volume of the gas = V_2=?

Initial pressure of the gas =P_1=0.8 atm

Final volume of the gas = P_2=0.5 atm

Using Boyle's law:

P_1V_1=P_2V_2

0.8 atm \times 3.5 L=0.5 atm\times V_2

V_2=5.6 L

Hence,the correct answer is option A.
