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.

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."
