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

Text Solution

Verified by Experts

We are given that `V_(1) =120 mL " " p_(1)=1.2` bar
`T= 35^(@)C " " V_(2) =180` mL
We are to calculate the pressure, `p_(2)`
According to Boyle.s law :
`p_(1) V_(1) =p_(2) V_(2) " " 1.2 xx 120 = p_(2) xx180`
`p_(2) = (1.2 xx 120)/(180) =0.8` bar
