Marks: +1, -0
A vessel of 120 mL capacity conta ins a certain amount of gas of 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?
Solution:  
Since temperature and amount of gas remain constant, therefore, Boyle’s law is applicable.
P1V1P_1V_1 = P2V2P_2V_2
P1P_1 = 1.2 bar, P2P_2 = ? V1V_1 = 120 mL, V2V_2 = 180 mL
∴ 1.2 × 120 = P2P_2 × 180 ⇒ P2P_2 = 1.2×120180\frac{1.2 \times 120}{180} = 0.8 bar
