Question

A container containing 5.00 L of a gas is collected at 100 K and then allowed to expand to 20.0 L. What must the new temperature be in order to maintain the same pressure (as required by Charles’ Law)

    Answer:

    400 K

    Explanation:

    Charles’s law states:

    A determined volume of a gas is directly proportional to its temperature, while we have constant pressure.

    V₁ / T₁ = V₂ / T₂

    We replace data:

    5 L / 100K = 20L / T₂

    T₂ = 20L . 100K / 5 L

    T₂ = 400 K

    The volume was quadrupled, so the temperature did.

    If we want T° at Celsius degree:

    400 K – 273 = 127°C
