a vessel of 120 mL capacity contains a certain amount of gas at 1.2 bar pressure and `35^(@)C`. The gas is transferred to another vessel of volume 180 mL at `35^(@)C`. What would be its pressure?

Text Solution

Verified by Experts

Given
`P_(1)=1.2` bar
`V_(1)=120` mL
`T=35^(@)` or `308.15K`
`P_(2)=?`
`V_(2)=180` mL
`T_(2)=35^(@)C` or `308.15K`
`thereforeP_(2)=(P_(1)V_(1))/(V_(2))=0.8` bar
