What Happens to fluids under pressure?

Question

(the effects of exerting pressure on air and water in closed systems)

Answer 1

Fluids include both gas and liquid states. Fluids are simply the physical state of matter wherein the molecules are not locked in position with respect to each other. Solids, on the other hand, have their molecules locked into position; so they can't do much more than vibrate in place.

The difference between gas and liquid is that gas molecules can go just about anywhere in space and liquid molecules are more or less confined to move around among their own molecules. In other words gas molecules have more freedom to move around than liquids. Also, in general, gas molecules are farther away from each other than liquid molecules.

Because gas molecules are typically farther apart under normal pressures and temperatures, they can be compressed rather easily. This means that putting gas under pressure in a confined container (like a thermos bottle) will push the molecules closer together. And, as we push those molecules closer together, they start to run into each other more as they move about...this creates heat and raises the temperature of the gas.

Liquid molecules are already pretty close together. So, in general, attempts to push them closer together under pressure typically do not work. Thus, we call liquids, like water, incompressable. Because of this incompressability, whatever pressure we put on top of a liquid in a contained space (like that thermos bottle), will be transmitted throughout the liquid.

For example, if we push on top with ten pounds per square inch of pressure, that 10 psi will be pushing everywhere throughout that liquid. Thus, there will be 10 psi everywhere on the side of the thermos with the liquid in it.

In a nutshell: pushing on gas (like air) will compress and heat it. Pushing on liquid (like water) will not compress it or heat it, but it will transmit that pressure throughout the liquid.

Answer 2

If you put enough pressure on fluids but keep the temperature and the volume same, then theoratically, they would first turn into a solid and eventually have temperature of 0 k (no movement of particles) and then you wont be able to compress it anymore because you can't have less than "no" movement.

This is impossible at room temperature. At room temperature, the temperature would be 298.13 k or 25 degrees C.

Answer 3

Heat

Answer 4

under relatively some tension no longer something ought to happen using fact the atoms cant pass. and it additionally relies upon on the density of the object. there are no longer lots effects. certainly, i dont think of there is any in any respect...

Answer 5

they explode
