A vessel of 120 mL capacity contains a certain amount of gas at 35°C

1.	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?
Answer» Here, temperature remains constant. Then for a certain amount of gas p₁V₁ = p₂V₂ 1.2 bar x 120 mL = P₂ x 180 mL or, p₂ = {1.2 bar x 120 mL}/{180 mL} = 0.8 bar

Answer»

Here, temperature remains constant. Then for a certain amount of gas

p₁V₁ = p₂V₂

1.2 bar x 120 mL = P₂ x 180 mL

or, p₂ = {1.2 bar x 120 mL}/{180 mL}

= 0.8 bar
