Q4 what is floatation?
Answers
Answer:
Hope it helps :)
Explanation:
chromatology - a process in which a chemical mixture carried by a liquid or gas is separated into components as a result of differential distribution of the solutes as they flow around or over a stationary liquid or solid phase.
sublimation - Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state.The reverse process of sublimation is deposition or desublimation, in which a substance passes directly from a gas to a solid phase.
filtration - Filtration is technically defined as the process of separating suspended solid matter from a liquid, by causing the latter to pass through the pores of a membrane, called a filter.
decantation - Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. An incomplete separation is witnessed during the separation of two immiscible liquids.
cyclone - In meteorology, a cyclone (/ˈsaɪ. kloʊn/) is a large scale air mass that rotates around a strong center of low atmospheric pressure. Cyclones are characterized by inward spiraling winds that rotate about a zone of low pressure.
separation - the act or process of separating : the state of being separated. 2a : a point, line, or means of division. b : an intervening space : gap the separation between wheel spokes. 3a : cessation of cohabitation between a married couple by mutual agreement or judicial decree.
winnowing - Winnowing is an agricultural method developed by ancient cultures for separating grain from chaff. It can also be used to remove pests from stored grain. Winnowing usually follows threshing in grain preparation.
two difference between mixture and compound - Compound are substances which can be formed by chemically combining two or more elements. Mixtures are substances that are formed by physically mixing two or more substances. Compounds can be of three types, which are: covalent compounds, metallic compounds and ionic compounds.
floatation - the act, process, or state of floating. 2 : an act or instance of financing (such as an issue of stock)
Answer:
Q 1:-chromatology :-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.
sublimation:-Sublimation is a chemical process where a solid turns into a gas without going through a liquid stage. ... The meaning of sublimation is causing something to change from solid to a gas, without becoming a liquid.
Explanation:
filtration:-
the action or process of filtering something.
"small particles are difficult to remove without filtration"
what is winnowing:-blow a current of air through (grain) in order to remove the chaff.
"a combine cuts, threshes, and winnows the grain in one operation"
decantation cyclone separation:-Cyclone separators or simply cyclones are separation devices (dry scrubbers) that use the principle of inertia to remove particulate matter from flue gases. Cyclone separators is one of many air pollution control devices known as precleaners since they generally remove larger pieces of particulate matter.
difference between mixture and compound:-
Mixtures are the impure substances, made up of two or more physically mixed substances and not in the fixed ratio. Compounds are the pure form, made up of two or more chemically mixed elements and in a fixed ratio. Mixtures can be homogenous or heterogeneous in nature, but compounds are generally homogenous.
