Suppоse а gаs-filled incаndescent light bulb is manufactured sо that the gas inside the bulb is at atmоspheric pressure when the bulb has a temperature of 20.0 0C. Find the gauge pressure inside such a bulb when it is hot, assuming its average temperature is 60.0 0C (an approximation) and neglecting any change in volume due to thermal expansion or gas leaks.
