A balloon contains 1.2L of air at a particular temperature and 90 cm Hg pressure. What will be the volume of air if the pressure is reduced to 70 cm Hg, while keeping the temperature constant?

Text Solution

Verified by Experts

Given, `P_(1)=90cm" Hg",P_(2)=70cm" "Hg,V_(1)=1.2L&V_(2)=?`
For the relation, `P_(1)V_(1)=P_(2)V_(2)`, we have
`V_(2)=(P_(1)V_(1))/(P_(2))=(90" cm Hg"xx1.2L)/(70" cm Hg")=1.54L`.
thus, the volume of air at 70 cm Hg is 1.54 L.
