What is diffusion using particle theory?
Diffusion in gases When chemicals, like the smell of perfume or burning toast, are let loose in a room, the particles mix with the air particles. The particles of smelly gas are free to move quickly in all directions. They eventually spread throughout the whole room. This is called diffusion.
What is osmosis diffusion?
Osmosis is a specific type of diffusion; it is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration.
What is the formula of Graham’s law of diffusion?
Graham’s Law Formula Graham’s law states that the rate of diffusion or effusion of a gas is inversely proportional to the square root of its molar mass. See this law in equation form below. r ∝ 1/(M)½ or. r(M)½ = constant.
What is the meaning of gas diffusion?
Gaseous diffusion refers to the flow of matter when there is a difference in concentration of the material between the interior of the concrete and the external environment, or between different regions within a concrete mass.
What holds particles together?
The strong force binds quarks together within protons, neutrons, and other subatomic particles. Rather as the electromagnetic force is ultimately responsible for holding bulk matter together, so the strong force also keeps protons and neutrons together within atomic nuclei.
How is osmosis different to simple diffusion?
Diffusion is the movement of molecules from an area of high concentration to low; osmosis is the movement of water from an area with less concentration dissolved particles to one with higher.
How is Graham’s law used in everyday life?
One can easily observe the application of Graham’s law in real life by lighting an incense stick and observing the behaviour of the smoke molecules generated by it. This is because the smoke coming out of the burning incense stick spreads in the surroundings quickly with the help of the diffusion process.
Why are gases highly diffusible?
The high diffusibility of gases is due to high kinetic energy of gaseous molecules.
Can a gas diffuse into another gas?
Diffusion of gases allows you to spread the smell of lot of things quickly across the room. Some examples can be: The fragrance of perfume being one of the best examples of diffusion of gases. The smell of perfume diffuses in the air so fast that you can smell it from across the room.
