Difference Between Molecular Motion and Diffusion

The main difference between molecular motion and diffusion is that molecular motion is the movement of molecules in a substance here and there without any external influence whereas diffusion is the movement of molecules from a highly concentrated region to a lowly concentration region.

What is molecular motion?

Molecular motion is defined as the movement of constituent particles or molecules in a certain direction. The molecular motions are affected by heat and temperature. This is because the temperature is the measurement of the average kinetic energy of the molecules and represents the motion of molecules.

What is the difference between molecular motion and energy?

the relationship between molecular motion and kinetic energy is that the faster the molcules are moving, the higher the kinetic energy is. ... The relationship between the two is that the higher the molecular motion is, the higher the temperature is.

What is an example of molecular diffusion?

Perfume is sprayed in one part of a room, yet soon it diffuses so that you can smell it everywhere. A drop of food coloring diffuses throughout the water in a glass so that, eventually, the entire glass will be colored. Carbon dioxide bubbles diffuse from an open soda, leaving it flat. ...

What is the difference between diffusion and effusion?

Diffusion occurs when gas molecules disperse throughout a container. Effusion occurs when a gas passes through an opening that is smaller than the mean free path of the particles, that is, the average distance traveled between collisions. Effectively, this means that only one particle passes through at a time.

How is molecular motion increases?

In the kinetic theory of gasses, increasing the temperature of a gas increases in average kinetic energy of the molecules, causing increased motion. ... In the kinetic theory of gasses, increasing the temperature of a gas increases in average kinetic energy of the molecules, causing increased motion.

What is the relationship between molecular motion and heat?

As the temperature increases, the kinetic energy of the molecules of the liquid increases. The movement of the molecules gradually overcomes forces of attraction between the molecules, with the result that they have greater freedom to move, over greater volumes. Thus the liquid expands.

What is define diffusion?

Diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration.

What is random molecular motion called?

Brownian motion, or pedesis (from Ancient Greek: πήδησις /pɛ̌ːdɛːsis/ "leaping"), is the random motion of particles suspended in a medium (a liquid or a gas).

At which temperature does all molecular motion steps?

All molecular motion stops at 0 degrees Kelvin or -273.15 degrees Celsius. The temperature at which all molecular motion ceases is known as...

What are 2 examples of diffusion?

10 examples of diffusion in everyday life

• You can smell perfume because it diffuses into the air and makes its way into your nose.
• Cigarette smoke diffuses into the air.
• A few crystals of potassium permanganate in water will diffuse and turn the water purple.
• Leave a soda bottle open and the carbon dioxide bubble will diffuse and leave it flat.

What are the 3 types of diffusion?

1 Answer. Simple diffusion, osmosis and facilitated diffusion.

What are the two types of diffusion?

Diffusion can be classified into two main types: Simple diffusion and facilitated diffusion.
