Small particles or molecules suspended in a liquid or gas will move by what is called Brownian motion. Brownian motion is a random motion of particles resulting from collisions with other matter. Unless otherwise disturbed, Brownian motion will eventually diffuse the suspended particles evenly throughout the liquid or gas.

Why does viscosity vary with respect to temperature?
the increase in temperature increases the K.E of the molecules and distances among molecules therefore the force of friction decreases as the result of which molecules move faster and viscosity becomes decreased....
What happens to a fluid when it cools?
When a fluid cools, its molecules lose energy and move more slowly, causing the fluid to contract and become denser. Eventually, the fluid may reach its freezing point and solidify into a solid state.
In fluids at rest do molecules of the fluid move about?
In fluids at rest, the molecules of the fluid do not move about or flow in a particular direction as they are in equilibrium. The molecules still vibrate and rotate in place, but their overall position remains constant.
What happens to a fluids viscosity when it is heated?
When a fluid is heated, its viscosity typically decreases. This is because heating causes the molecules in the fluid to move more freely and rapidly, which reduces the internal friction between the molecules and leads to a lower viscosity.
What is convection transfered through?
Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it.
How do molecules move in fluid?
Molecules move in a fluid the same way they move through anything else. If the fluid is warmer, they move faster.
What happens to molecules in a heated fluid?
In a heated fluid, molecules gain kinetic energy, causing them to move faster and collide more frequently. This increased movement results in the expansion of the fluid, as the molecules move apart from each other. Additionally, the increased temperature can lead to changes in the physical state of the fluid, such as boiling or evaporation.
What happens to a fluid when it heats?
When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules. When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules.

Because the phospholipid molecules and some proteins are free to move the plasma membrane is said to be?
Because the phospholipid molecules and some proteins are free to move, the plasma membrane is said to be fluid, allowing for flexibility and dynamic changes in its structure. This fluidity is essential for various cellular processes such as cell communication and transport of molecules across the membrane.

What happens as the molecules in a liquid move around?
As molecules in a liquid move around, they flow past each other, creating a fluid-like behavior. The molecules continuously collide with each other and with the boundaries of the container, leading to the pressure and viscosity characteristics associated with liquids.
What happens to a fluid when temperature increases?
The particles within the liquid begin to accelerate, and colide at a faster rate as the temperature of the solution increases. This causes the particles to move further, and further away from each other as the inter-molecular bonds holding the molecules begin to weaken.
What happens when the density of a fluid gets hotter?
When the density of a fluid gets hotter, it usually decreases. This is because as the fluid gets hotter, its molecules gain energy and move farther apart, causing the fluid to expand. This expansion leads to a decrease in density.
