    V₂ = 600 mL

    Explanation:

    Given dа ta:

    Initial volume = 300 mL

    Initial temperature = 400 K

    Final temperature = 800 K

    Final volume = ?

    Solution:

    The given problem will be solve through the Charles Law.

    According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

    Mathematical expression:

    V₁/T₁ = V₂/T₂

    V₁ = Initial volume

    T₁ = Initial temperature

    V₂ = Final volume

    T₂ = Final temperature

    Now we will put the values in formula.

    V₁/T₁ = V₂/T₂

    V₂ = V₁T₂/T₁

    V₂ = 300 mL * 800 K / 400 k

    V₂ = 240000 mL. K / 400 K

    V₂ = 600 mL
