Question
Suppose a gas-filled incandescent light bulb is manufactured from regular glass and with atmospheric pressure in it at 20.00°C. Its average temperature when hot is 63.42°C. Neglecting any change in
volume due to thermal expansion or gas leaks, its gauge pressure is calculated to be 0.1482 atm. The actual final pressure for the light bulb will be less than calculated because the glass bulb will
expand. What will the actual final gauge pressure be, taking this into account? The coefficient of volume expansion for regular glass is 27 x 10-6/°C. (Give your answer to at least four decimal
places.)
atm
Is this a negligible difference compared to the pressure difference induced by the temperature increase? (Note: We define negligible as a difference less than 0.01 atm.)
Yes
Ο No
