Explanation:

Based on Charles's law, the volume of a gas is directly proportional to absolute temperature. The formrula is:

V₁ / T₁ = V₂ / T₂

Where 1 represents the initial state and 2 the final state of the gas

Using the values of the problem:

V₁ = 10.0L

T₁ = 127°C + 273.15K = 400.15K

V₂ = 20.0L

Thus, replacing in the formula:

10.0L / 400.15K = 20.0L / T₂

T₂ = 800K

In Celsius:

800K - 273.15 = 526.85K
