A sample of chlorine gas is held at a pressure of 1023.6 Pa. When the pressure is decreased to 811.4 Pa the volume is 25.6 L. What was the original volume?

V1 = 20.3L

Explanation:

P2 = 811.4Pa

V2 = 25.6L

P1 = 1023.6Pa

V1 = ?

To solve this question, we'll have to use Boyle's law which states that the volume of a fixed mass of gas is inversely proportional to its pressure provided that temperature remains constant.

Mathematically,

V = k / P, k = PV

P1 × V1 = P2 × V2 = P3 ×V3 ==Pn × Vn

P1 × V1 = P2 × V2

Solve for V1

V1 = (P2 × V2) / P1

V1 = (811.4 × 25.6) / 1023.6Pa

V1 = 20771.84 / 1023.6

V1 = 20.29 = 20.3L

The initial volume was 20.3L

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
