He was literally so scared of the Mountain/Cersei/Jaime that he needed to expel gas.

When an asteroid approaches the sun, its surface heats enough to expel gas and other material, acting like a natural thruster.

SAFER is equipped with very small thrusters that expel gas and propel an astronaut in the direction he or she wants to go.

It is common for big black holes to expel gas outward, but rare to have such a close, resolved view of these events.

During bulk fermentation straight-dough recipes may instruct a baker to "punch down" or "deflate" the dough, while artisan bakers will use terms like "stretching", "folding", and "degassing", meaning to expel gas from the carbon dioxide bubbles that have formed. Sponge doughs will need multiple mixing periods. Overproofing occurs when a fermenting dough has rested too long. Its bubbles have grown so large that they have popped and tunneled, and dough baked at this point would result in a bread with poor structure.

A diaphragm type gas meter, cutaway sketch from 1900 These are the most common type of gas meter, seen in almost all residential and small commercial installations. Within the meter there are two or more chambers formed by movable diaphragms. With the gas flow directed by internal valves, the chambers alternately fill and expel gas, producing a nearly continuous flow through the meter. As the diaphragms expand and contract, levers connected to cranks convert the linear motion of the diaphragms into rotary motion of a crank shaft which serves as the primary flow element.

Stellar winds and radiation pressure from the massive stars begins to drive away the hot ionized gas at a velocity matching the speed of sound in the gas. After a few million years the cluster will experience its first core-collapse supernovae, which will also expel gas from the vicinity. In most cases these processes will strip the cluster of gas within ten million years and no further star formation will take place. Still, about half of the resulting protostellar objects will be left surrounded by circumstellar disks, many of which form accretion disks.

As the external pressure decreases, the difference in pressure between the gas within the body and the atmosphere outside is higher, and the urge to expel gas to relieve the pressure is greater. Consistent with Boyle's law, controlling for dietary variance, the amount of gas produced is constant in mass, but the volume increases as the external pressure decreases. The feeling of fullness or need to expel brought on by this differential in atmospheric pressure has been verified by studies involving military pilots subjected to pressure changes simulating flight.

A Friend of the Earth is the story of Tyrone O'Shaughnessy Tierwater, a U.S. citizen born in 1950, half Irish Catholic and half Jewish ("I'm a mess and I know it. Jewish guilt, Catholic guilt, enviro-eco-capitalistico guilt: I can't even expel gas in peace."), whose personal tragedy fits in with, and adds to, the gloomy atmosphere created in the novel. Egged on by Andrea, the woman he loves, he becomes a committed "Earth Forever!" activist (an allusion to the radical environmental group Earth First!) in the 1980s, is imprisoned for ecotage, but eventually cannot change anything.

The intake tube takes in air and mixes it with fuel to combust, and also controls the expulsion of exhaust gas, like a valve, limiting the flow but not stopping it altogether. While the fuel-air mixture burns, most of the expanding gas is forced out of the exhaust pipe of the engine. Because the intake tube(s) also expel gas during the exhaust cycle of the engine, most valveless engines have the intakes facing backwards so that the thrust created adds to the overall thrust, rather than reducing it. The combustion creates two pressure wave fronts, one traveling down the longer exhaust tube and one down the short intake tube.

The sigmoid colon begins at the superior aperture of the lesser pelvis, where it is continuous with the iliac colon, and passes transversely across the front of the sacrum to the right side of the pelvis. (The name sigmoid aptly means S-shaped.) It then curves on itself and turns toward the left to reach the middle line at the level of the third piece of the sacrum, where it bends downward and ends in the rectum. Its function is to expel solid and gaseous waste from the gastrointestinal tract. The curving path it takes toward the anus allows it to store gas in the superior arched portion, enabling the colon to expel gas without excreting faeces simultaneously.
