In particle theory why do fluids flow?

Answer 1

I may be wrong, but i am trying to help. In the particle theory fluids flow because the particle theory states that

All matter is composed of particles

Particles are in constant motion

All articles are attracted to one another

Particles move faster as they gain energy

So, fluids have particles and depending on how much particles the fluid contains will determine how fast or slow it flows. A fluid will flow faster if the partcles are rubbing against each other and attract to eachother. if they are always moving and trying to do this the subsance will gain energy and flow faster. The opposite if something flows slower.

is that an okay answer? hope it is:)

Answer 2

In particle theory, fluids flow because the particles within the fluid (like atoms or molecules) have kinetic energy, which allows them to move past one another. The movement of these particles leads to the macroscopic behavior of fluid flow, resulting in properties such as viscosity and fluidity.
