Answer:
Explanation:
Given data:
Initial pressure P1 = 4 atm
Final pressure P2 = 0.2 atm
Final volume V2= 500 L
Solution:
First of all we will calculate the initial volume of gas.
P1V1 =P2V2
V1 = P2V2 / P1
V1 = 0.2 atm Ć 500 L / 4 atm
V1 = 25 L
We can see that in given problem as the volume is increases from 25 L to 500 L pressure is goes to decrease from 4 atm to 0.2 atm.
According to the boyle's law, The volume of given amount of gas is inversely proportional to its pressure, at constant temperature.
Ā Vā 1/p
Ā V = K/P
Ā PV= K
so,
P1V1 Ā = K Ā Ā Ā and Ā P2V2 = K
or
P1V1 =P2V2
