Is the pressure of gas at any point within mostly due to particles collisions rather than weight of gas above point considered?
What is the atmospheric pressure at sea level ? What is the atmospheric pressure at 5 miles up ? What is the difference between "due to particle collisions" and "due to weight of gas above" ?Sultanphys said:Is the pressure of gas at any point within mostly due to particles collisions rather than weight of gas above point considered?
The pressure is always exclusively due to particle collisions. The weight of the gas above only changes the frequency of particle collisions, by changing the number of particles per unit volume.Sultanphys said:Is the pressure of gas at any point within mostly due to particles collisions rather than weight of gas above point considered?
Huh?Sultanphys said:So for a gas confined in a balloon in non gravitational field the pressure of the gas at any point will not change considerably than in case if in gravity field,while this is not the case in liquids ,is this right?

The pressure of weightless fluids is zero. This is because weightless fluids have no mass, and pressure is defined as force per unit area, where force is the product of mass and acceleration. Since weightless fluids have no mass, there is no force acting on them, and therefore no pressure.
Pressure does not change in weightless fluids. As mentioned before, weightless fluids have no mass, and therefore no force acting on them. This means that the pressure remains constant throughout the fluid.
No, weightless fluids cannot exert pressure. As mentioned before, pressure is defined as force per unit area, and weightless fluids have no mass or force acting on them. Therefore, they cannot exert pressure.
The pressure of weightless fluids cannot be measured directly, as they have no mass or force acting on them. However, scientists can measure the pressure exerted by objects on weightless fluids, such as a spacecraft or a diver, and use this information to calculate the pressure of the weightless fluid.
Studying the pressure of weightless fluids is important in understanding the behavior of fluids in space, such as in spacecraft or in microgravity environments. This knowledge is also useful in designing more efficient systems for fluid transportation and storage, as well as in the development of new technologies for space exploration.
