(a) Find the gauge pressure inside such a bulb in atmospheres when it is hot, assuming its average temperature is 65.0°C (an approximation) and neglecting any change in volume due to thermal expansion or gas leaks. (b) The actual final pressure for the light bulb will be less than calculated in part (a) because the glass bulb will expand. What will the actual final gauge pressure be in atmospheres, taking this into account?
