2. A gas has volume of 4.2L at 110 kPa. If temperature is constant, find the pressure of gas when the volume is change to 11.3L.

muminat

Answer:

40.88 kPa.

Explanation:

Given that,

Volume, V₁= 4.2 L

Pressure, P₁ = 110 kPa

We need to find the pressure of the gas when the volume is changed to 11.3L at constant temperature.

According to Boyle's law, at constant temperature, volume is inversely proportional to the pressure. Mathematically,

$P_1V_1=P_2V_2\\\\P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{4.2\ L\times 110\ kPa}{11.3\ L}\\\\P_2=40.88\ kPa$

So, the new pressure is 40.88 kPa.
