- 1What is a mixtureA mixture is two substance or more that is mixed and can be separated back to its original particular
- 2What is a solutethe minor component in a solution, dissolved in the solvent.
- 3What is a solventable to dissolve other substances
- 4What is a solutiona liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent).
- 5What is concentrated solutionConcentrated solution is a solution that contains a large amount of solute relative to the amount that could dissolve
- 6What is a dilute solution(of a liquid) made thinner or weaker by having had water or another solvent added to it.
- 7What is flitrationthe action or process of filtering something.
- 8What is magnetic separationMagnetic separation is a process in which magnetically susceptible material is extracted from a mixture using a magnetic force. This separation technique can be useful in mining iron as it is attracted to a magnet
- 9What is sievingan instrument with a meshed or perforated bottom, used for separating coarse from fine parts of loose matter, for straining liquids,
- 10What is evaporationEvaporation is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure.
- 11What is concentrationThe change of a gas or vapor to a liquid, either by cooling or by being subjected to increased pressure. When water vapor cools in the atmosphere
- 12What is condensationIn chemistry, the number of molecules or ions in a given volume of a substance
- 13What is plasmathe colourless fluid part of blood, lymph, or milk, in which corpuscles or fat globules are suspended.
- 14What is red blood cellslacks a nucleus, and transports oxygen and carbon dioxide to and from the tissues.
- 15What is separationthe action or state of moving or being moved apart.
- 16What is magnetic forcesMagnetic force, attraction or repulsion that arises between electrically charged particles because of their motion.
- 17What is gravity separationGravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical
- 18What is crystallisationCrystallisation is a separation technique that is used to separate. a solid that has dissolved in a liquid and made a solution
- 19What is chromatographya technique for the separation of a mixture by passing it in solution or suspension through a medium in which the components move at different rates.
- 20What is decantationDecantation is a process for the separation of mixtures, by removing a layer of liquid, generally one from which a precipitate has settled
