Gases flow anywhere they want to. This is one of the special properties of gases. They do NOT have a definite volume or shape. They take the shape of their container and fill the volume of that container.
gasses, liquids and solids
"Trace gasses" are elements which are present in a sample, but in relatively very small amounts.
The solubility of each gas in water is different.
They are condensed materials because that's what makes them what they are. The more condensed a substance is the less it can flow. Gases are the least condensed, so they flow the easiest, followed by fluids, then solids.
Because the gasses that eventually cause acid rain are everywhere in the atmosphere and clouds. As wind patterns move over the earth, they carry these gasses everywhere they go. The rain falls where it will. The acid rain gasses could come from hundreds or thousands of miles away.
The flow of exhaust gasses
gasses, liquids and solids
To allow gasses or liquids to flow only in one direction.
pyroclastic flow
Yes. Pyroclastic flows can contain toxic gasses such as sulfur dioxide.
Fluids have the ability to flow. Fluids are Liquids and Gasses.
cutaneous
Dampers are used to regulate the flow of air or gasses in ductwork and chimneys.Without dampers the flow in ducts would only be regulated by the fan speed, the flow in chimneys would be dependent on the developed draft, and neither would be controllable directly.
Air Switching Valve Operation: A circular-stemmed device used to control the flow of air/fuel mixture in and the flow of burned gasses out of the engine.
The throttle manages the flow of fluid or gasses by constriction or obstruction. By constricting the flow it determines the engine's power outlet. The throttle body is part of the air intake system.
Simply put the intake manifold is on one side and the exhaust is on the other allowing the engine to have a more direct passage of gasses. All V 8 engines are automatically cross flow.
The explosive force of an explosive eruption comes from gasses trapped in the magma. Runny magma does not hold gasses very well, and so those gasses escape before the magma erupts. The runny magma can also easily flow to the surface without getting stuck and having to be blown out, unlike thicker types of magma.
