    Final pressure of light bulb is 2.03 atm.

    Explanation:

    Given dа ta:

    Initial pressure = 1.34 atm

    initial temperature = 26 °C

    Finial temperature = 179 °C

    Final pressure = ?

    Formula:

    P1/T1 = P2/T2

    Solution:

    First of all we will convert the °C into kelvin.

    179 + 273 = 452 K

    26 + 273 = 299 K

    P2 = P1*T2/T1

    P2 = 1.34 atm. 452 K / 299 K

    P2 = 605.68 atm / 299

    P2 = 2.03 atm
