A vessel of 120ml capacity contains a certain amount of gas at 35°C and 1.2 bar pressure. The gas is transferred to another vess

Rainbow [258]

Given parameters:

Initial volume = 120ml

Initial temperature = 35°C

Initial pressure = 1.2bar

Final volume = 180ml

Final temperature = 35°C

Unknown:

Final pressure = ?

To solve this problem, we apply the combined gas law. The expression is given below;

$\frac{P_{1}V_{1} }{T_{1} } = \frac{P_{2}V_{2} }{T_{2} }$

Where P₁ is the initial pressure

P₂ is the final pressure

V₁ is the initial volume

V₂ is the final volume

T₁ is the initial temperature

T₂ is the final temperature

We need to convert the parameters to standard units

take the volume to dm³;

1000ml = 1dm³

120ml = $\frac{120}{1000}$ dm³ = 0.12dm³ = initial volume

Final volume;

1000ml = 1dm³

180ml = $\frac{180}{1000}$ dm³ = 0.18dm³

Now, the temperature;

K = 273 + °C

Initial temperature = 273 + 35 = 308k

Final temperature = 308k

We then input the parameters into the equation;

$\frac{1.2bar x 0.12 }{308} = \frac{P_{2} x 0.18 }{308}$

Solving for P₂;

P₂ = 0.8bar

The new pressure or final pressure in the vessel is 0.8bar
