Molecules, due to constant thermal motion, enables them to move from one region to another with a velocity that depends on their mass, shape, the temperature and viscosity of the medium.
Brownian motion is also a factor - this is where the bombardment of the molecules are taken into consideration (colliding with one another).

Explain what determines the viscosity of a liquid?
the shape and size of the molecules that the fluid consists of, if they are big, wavy molecules then the liquid will be viscous because the molecules struggle to move over each other.
Explain why the term fluid mosaic model is used to describe the plasma membrane?
the arrangement of the molecules that make up a cell mebrane
How do you describe the motion of atoms in a solid?
Atoms move more freelythan they would in a soild or a liquid.
What is fluid mosaic pattern?
The lipids molecules that form the membrane are fluid. They can move about relative to one another in a fluid manner. Some of the proteins are also free to move about so that the mosaic or pattern of lipids and proteins changes. Because of these characteristics scientists call their model of the dynamic cell membrane the fluid the fluid mosaic model.
Describe the movement of atoms or molecules in liquid form?
why is a dance floor a good analogy forte movement of atoms in a liquid
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.
Describe the water molecules move through the cell membrane during osmosis?
Describe how water molecules move through the cell membrane during osmosis?
Describe what is happening to water molecules as ice melts?
they move faster
What happens to molecules in a heated fluid?
Molecules will rapidly spread apart and move in every direction in the presence of a heated fluid, and tightly bunch up in cooler fluids.
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?
fluid mosaic
What is the name of the model developed by scientists to describe the arrangement of molecules within this structure?
Fluid mosaic model.
Describe the motion of molecules of a substance change as the energy is increased?
As energy increases molecules begin to move faster and shake more vigorously if you take energy out molecules do the opposite.
Explain what determines the viscosity of a liquid?

Explain why the term fluid mosaic model is used to describe the plasma membrane?
the arrangement of the molecules that make up a cell mebrane
How do molecules move in a fluid?
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.
Describe how sound waves are travel?
Sound waves are caused by vibrations and travel as longitudinal waves which cause by the vibration of the molecules in air (the molecules dont actually move)
