Answer:

12,500 L

Step-by-step explanation:

Because you are dealing with volume and temperature, you need to Charles' Law to find your missing value. The equation looks like this:

V₁ / T₁ = V₂ / T₂

In this equation, "V₁" and "T₁" represent the initial volume and temperature. "V₂" and "T₂" represent the final volume and temperature. You can plug the given values into the equation and simplify to find the final volume of the gas.

V₁ = 10,000 L V₂ = ? L

T₁ = 20 °C T₂ = 25 °C

V₁ / T₁ = V₂ / T₂ <----- Charles' Law equation

(10,000 L) / (20 °C) = V₂ / (25 °C) <----- Insert values

500 = V₂ / (25 °C) <----- Divide 20 from 10,000

12,500 = V₂ <----- Multiply both sides by 25
