Its average temperature when hot s 50.00 Neglecting any change in volume due to thermal expansion or gas leaks, its gauge pressure is calculated to be 0.1023 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? (Give your answer to 4 decimal places. .2558 X atmIs this a negligible difference compared to the pressure difference induced by the temperature increase? Yes No Additional Materials Reading 6.

Note that the air is at 37.0oC body temperature) and atmospheric pressure ume of air 7.86e-2 mo Additional MaterialsExplanation / Answer
Here , initially ,
gauge pressure = 0.1023 atm
P1 = 0.1023 + 1
P1 = 1.1023 atm
T1 = 20 C
T1 = 293 K
finally ,
T2 = 50 C = 323 K
Now, using ideal gas equation
P1/T1 = P2/T2
1.1023/293 =P2/323
P2 = 1.215 atm
final gauge pressure = P2 - 1
final gauge pressure = 1.215 - 1
final gauge pressure = 0.215 atm
the final gauge pressure is 0.215 atm
no, this pressure change is not negligible
