The original volume and pressure of
a gas sample were 5.0 L and 60. kPa.
The pressure was halved while tem-
perature was kept constant. Find the
new volume

Answer 1

Answer:

10 L

Explanation:

We are given;

• Initial volume, V1 as 5.0 L
• Initial pressure, P1 as 60 kPa
• Final pressure, P2 as 30 kPa (1/2 × 60 kPa)

We are required to calculate the new volume.

• In this case we are going to use the Boyle's law.
• According to the Boyle's law, the volume of a fixed mass of a gas varies inversely as its pressure at a constant temperature.

• That is, P α 1/V

At two varying pressure and volume of a gas;

P1V1 =  P2V2

Rearranging the formula, we can calculate the new volume;

V2 = P1V1 ÷ P2

    = (60 kPa × 5.0 L) ÷ 30 kPa

    = 10 L

Therefore, the new volume is 10 L
