Brownian Motion Brownian motion is the physical phenomenon that tiny particles immersed in a fluid move about randomly. A fluid can be a liquid or a gas. Brownian movement, an example of diffusion, supports the kinetic theory of matter. Examples of Brownian movement are movement of smoke particles in air movement of pollen grains in … Read more
Diffusion in Gas (Diffusion in Gas) Observation The brown colour bromine vapour spreads evenly throughout the gas jar in a few minutes Bromine vapour is made of tiny and discrete molecules that move randomly to fill up space. Bromine vapour moves randomly and diffuses in all directions in air from areas of higher concentration to … Read more
Diffusion in Liquid (Diffusion in Liquid) ObservationThe purple colour of potassium manganate(VII) fills up the entire test tube after a few hours Diffusion has taken place in the liquid. The rate of diffusion of the particles in water is faster than the diffusion rate of particles in solid. The occurrence of diffusion proves that potassium … Read more
Diffusion in Solid Diffusion in Solid Observation The blue colour of copper(II) sulphate fills up the entire test tube after a few days Copper(II) sulphate crystals are made of copper(II) ions and sulphate ions which are tiny and discrete. The particles in the copper(II) sulphate crystal will separate to become ions and diffuse randomly upwards … Read more
Proof of Particle Theory of Matter – Diffusion In SPM, you need to know diffusion is one of the proofs of the particle theory of matter. the definition of diffusion. diffusion in solid, liquid and gas factors that affect the rate of diffusion and the related experiments. What is Diffusion? Diffusion is a process of … Read more
Matter is anything that occupies space and has mass. The particle theory of matter states that matter is made up of a large number of tiny and discrete particles. Particle Theory of Matter: Matter is made up of a large number of tiny and discrete particles. Types of Particles Particles can exist as atoms, molecules … Read more
