Question

what is pasturisation ,sublimation, distillation, saturation and concentration.​

Answer 1

Answer:

1). Pasteurization or pasteurisation is a process in which certain packaged and non-packaged foods (such as milk and fruit juice) are treated with mild heat, usually less than 100 °C (212 °F), to eliminate pathogens and extend shelf life. The process is intended to stabilize foods by destroying or inactivating organisms and enzymes that contribute to spoilage, including vegetative bacteria but not bacterial spores. Since pasteurization is not sterilization, and does not kill spores, a second "double" pasteurization will extend the quality by killing spores that have germinated.

2). Sublimation (phase transition), the change from solid to gas without passing through the liquid phase. For example co2 (dry ice ), ammonium cloride, camphor etc.

3). Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components in the mixture. In either case, the process exploits differences in the volatility of the mixture's components. In industrial chemistry, distillation is a unit operation of practically universal importance, but it is a physical separation process, not a chemical reaction.

4). Saturation (chemistry) a property of hydrocarbons, triglycerides containing only saturated fatty acids .

5). In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration. A concentration can be any kind of chemical mixture, but most frequently solutes and solvents in solutions. The molar (amount) concentration has variants such as normal concentration and osmotic concentration.

Answer 2

Explanation:

⭕pasturisation : partial sterilization of a product, such as milk or wine, to make it safe for consumption and improve its keeping quality.

⭕Sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

⭕Distillation is the the action of purifying a liquid by a process of heating and cooling.

⭕Saturatation is the state of being saturated or the action of saturating.

⭕concentration is the abundance of a constituent divided by the total volume of a mixture.
