Suppose a gas-filled incandescent light bulb is manufactured so that the gas inside the bulb is at atmospheric pressure when the bulb has a temperature of 20.0°C. (a) Find the gauge pressure, in standard atmospheres, inside such a bulb when it is hot, assuming its average temperature is 60.5°C and neglecting any change in volume due to thermal expansion. (b) The actual final pressure for the light bulb will be less than calculated in part (a) because the glass bulb will expand a small amount. What will the actual final gauge pressure be, in standard atmospheres, assuming the thermal coefficient of volume expansion is 2.7 x 10$°C?

Suppose a gas-filled incandescent light bulb is manufactured so that the gas inside the bulb is
at atmospheric pressure when the bulb has a temperature of 20.0°C.
(a) Find the gauge pressure, in standard atmospheres, inside such a bulb when it is hot,
assuming its average temperature is 60.5°C and neglecting any change in volume due to
thermal expansion.
(b) The actual final pressure for the light bulb will be less than calculated in part (a) because
the glass bulb will expand a small amount. What will the actual final gauge pressure be, in
