Question

The volume of a fixed mass of a gas at 2atm pressure is 20L. What will be its volume if the
the pressure increased 4 times without changing its temperature ?
​

Answer 1

Answer:

5L

Explanation:

from pv=nRT

p is pressure v is volume

nRT is constant so P is inversely proportion to v

p1/p2=v2/v1

2/4(2)=v2/20

2/8=v2/20

5=v2

Answer 2

Answer:

5 L

Explanation:

from PC=nRT p is pressure V is volume. nRT is constant so p is inversely. proportion to v. p1/p2 =V2/v1. 2/4 (2)=V2/20. 5 =V2
