Question

Suppose a gas-filled incandescent light bulb is manufactured so that the gas inside the bulb is at atmospheric pressure (absolute pressure) when the bulb has a temperature of 19.3°C. (Enter your answers to at least four significant figures.)

Answer 1

As, the question is incomplete, so I'm telling u the initiation , that how to start this question..

Date A c 19. 3 As Tempellata Temperature = = 19.3 + 273.16 Ti - 292.46K Pe = 1,01 x los pa to Ideal gas's law: » According According to fu= nRT - nis constant, became the light bulb have not gained or lost any air Note that R- Universal Thas Constant So that, PV = nR = constant . Piti - Pq Vz Vz (Note that size li - b I will not change). - 1.01 X 105 292,46 By this you can find final Absolute . Pressure (if Ty is given

Then , after calculating Final Absolute Pressure (P_{​​​​​​f});

You can calculate the Final gauge pressure P_{​​​​​​f.gauge} by:

Subtracting P_{​​​​​​i} from P_{​​​​​​f .}
