    Answer:

    100 kPa

    Explanation:

    This can be solved with one of the gases law. This law establishes that the pressure of the gas is directly proportional to its temperature: If we increase the temperature, the pressure will increase.

    In this case, we decrease the temperature, so its pressure will be lower.

    P₁ / T₁ = P₂ / T₂

    We convert T° to Absolutes Values

    27°C + 273 = 300 K

    -173°C + 273 = 100 K

    300 kPa / 300 K = P₂ / 100 K

    (300 kPa / 300 K) . 100K = P₂

    P₂ = 100 kPa

    This is the Charles Gay Lussac’s law.
