    1.8 L

    Explanation:

    Ideal gas law:

    PV = nRT

    where P is absolute pressure,

    V is volume,

    n is number of moles,

    R is the gas constant,

    and T is absolute temperature.

    Rearranging:

    V / T = nR / P

    Since n, R, and P are constant:

    V₁ / T₁ = V₂ / T₂

    1.5 L / (298.15 K) = V / (363.15 K)

    V = 1.8 L
