    T₂ = 150.03 K

    Explanation:

    Given dа ta:

    Initial volume of gas = 2.0 L

    Initial temperature = 353 k

    Final temperature = ?

    Final volume = 0.85 L

    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

    T₂ = V₂ T₁ / V₁

    T₂ = 0.85 L * 353 K / 2.0 L

    T₂ = 300.05 L. K / 2.0 L

    T₂ = 150.03 K
