Suppose a gas-filled incandescent light bulb is manufactured so that the gas inside the bulb is at atmospheric pressure (1 atm = 1.013 x 10' Pa) when the bulb has a temperature of 20.0 C. Find the gauge pressure inside such a bulb when it is hot, assuming its average hot temperature is 75.0 .C. gauge pressure when hot: Pa The actual final pressure of the light bulb will be different than calculated in the first question because the glass bulb will expand. What will the final actual gauge pressure be, taking this into account? The volume expansion coefficient for glass is B = 2.700 x 10-5 .C-1. final gauge pressure, accounting for glass expansion: Pa Question Credit: OpenStax College Physics
