Centrifugation is a process used to separate components of a liquid mixture by spinning it in a centrifuge. The centrifugal force generated by the spinning causes the heavier components of the mixture to settle to the bottom of the container, while the lighter components remain suspended in the liquid. Centrifugationis often used in laboratories to …
Sublimation is the process of a substance transitioning directly from a solid to a gas without passing through the liquid phase. Separation is the process of separating two or more substances from a mixture. Separation can be used to separate the components of a mixture as part of the sublimation process. For example, a solid …
A separating funnel is a piece of laboratory equipment used to separate two immiscible liquids. This can be done by taking advantage of their different densities. To separate kerosene and water using a separating funnel, the two liquids are poured into the funnel. The kerosene, being less dense, will collect at the top of the …

Fractional distillation is a method of separating a mixture of liquids into its components. It relies on the different boiling points of the components of the mixture. The mixture is heated until it reaches a temperature at which one of the components begins to vaporize, and the vapor is then collected and condensed back into …
Distillation is a process used to separate a liquid mixture into its component parts, or fractions. In the case of a salt solution, it is possible to separate the water from the salt by distillation. To perform a distillation, a round bottom flask is filled with the salt solution and attached to a condenser. The …
A pure substance is a material that is composed of only one type of atom or molecule. Examples of pure substances include elements such as gold, oxygen, and nitrogen, as well as compounds such as water, carbon dioxide, and table salt. A mixture is a material composed of two or more different substances that are …

The diffusion of perfume throughout a room. The diffusion of heat from a heater. The diffusion of sound waves from a speaker. The diffusion of molecules in a gas. The diffusion of light from a lamp. The diffusion of water molecules from a wet cloth
When iodine is heated, it produces vapour that can be collected in a test tube. To do this, the test tube should be inverted and placed over the source of heat. This allows the vapour to diffuse into the test tube. What is the relation between diffusion and movements of particles in different states of …
Sublimation is a process in which a solid turns directly into a gas without passing through the liquid state. It occurs when the particles of a solid absorb enough energy to break the bonds between them and enter the gas phase, bypassing the liquid phase entirely. Example :Naphthalene,iodine
When a substance is heated, its state changes. For example, when water is heated, it changes from a liquid to a gas (water vapour). As the temperature increases, the molecules of the substance gain more energy and move faster and faster. Eventually, the molecules move so quickly that they escape the attraction of the other …
