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 20.0ºC . (a) Find the gauge pressure inside such a bulbwhen it is hot, assuming its average temperature is 60.0ºC(an approximation) and neglecting any change in volume dueto 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 pressure be, taking this into account? Is this a negligible difference?

A worker pressurized a rigid pipe (with an inside diameter of 30 mm and length of 20 m)with dry air to check for leaks. The temperature and absolute pressure of the air in thepipe were 35°C and 205 kPa, respectively. After 24 hrs, the worker returns and finds outthat the absolute pressure drops to 183 kPa, while the air temperature inside the pipedecreases to 21°C. Has air leaked out of the pipe? If yes, calculate the mass of air thathas leaked out through the fittings. (Rair = 287.08 J / kgm K)
