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?

Explanation

Formula :
` P_1V_1 =P_2 V_2 `
` P_1 = 1.2` bar
` V_1 = 120 ml`
` V_2 = 180 ml`
`P_2 = ?`
`1.2 xx 120 = P_2 xx 180`
` P_2 =( 1.2 xx 12 )/( 18 )`
`=( 2.4)/(3) = 0.8 ` bar
