Question

What would the final volume of 40 L of gas at 80 pascals be if the pressure increases to 130 pascals?

Answer 1

Final volume, V2 = 24.62 L

Step-by-step explanation:

Given the following data;

Initial volume = 40 L

Initial pressure = 80 Pa

Final pressure = 130 Pa

To find the final volume V2, we would use Boyles' law.

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

`PV = K`

`P_(1)V_(1) = P_(2)V_(2)`

Substituting into the equation, we have;

`80 * 40 = 130V_(2)`

`3200 = 130V_(2)`

`V_(2) = \frac {3200}{130}`

`V_(2) = 24.62`

Final volume, V2 = 24.62 Liters
