    Answer:

    386.45 K

    Explanation:

    We can solve this problem by using Charles’ law, which states that at constant pressure:

    • V₁T₂=V₂T₁

    Where subscript 1 stands for initial conditions of volume and temperature, while 2 stands for the final ones. Meaning that in this case:

    • V₁ = 2.0 L
    • T₂ = ?
    • V₂ = 2.5 L
    • T₁ = 36 °C ⇒ 36 +273.16 = 309.16 K

    We input the data:

    • 2.0 L * T₂ = 2.5 L * 309.16 K

    And solve for T₂:

    • T₂ = 386.45 K
