Acontainer of gas has a volume of 3.5 l and a pressure of 0.8 atm. assuming the temperature remains constant, what volume of gas would result if the pressure was 0.5 atm?
a. 5.6 l
b. 2.2 l
c. 0.2 l
d. 1.8 l

Answer : The correct option is, (A) 5.6 L

Explanation :

Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

or,

where,

= initial pressure of gas = 0.8 atm

= final pressure of gas = 0.5 atm

= initial volume of gas = 3.5 L

= final volume of gas = ?

Now put all the given values in the above equation, we get:

Therefore, the final volume of the gas is 5.6 L.
