1.What is fractional distillation?
2. What is sublimation?
3. What is compound
4. What is mixture
Answers
Answer:
1. Fractional distillation is the separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize
2. Sublimation is the transition of a substance directly from the solid phase to the gas phase without passing through the intermediate liquid phase
3.a thing that is composed of two or more separate elements; a mixture.
4.a substance made by mixing other substances together.

Answer:
Fractional distillation is a process of separating two (or more) miscible liquids by distillation, the distillate being collected in fractions boiling at different temperatures.
The Changing of a solid directly into vapours on heating,and of vapours into solid on cooling is called as sublimation.
Compound is a pure substance made up of two or more elements combined chemically in a definite ratio.
A mixture is a substance which consists of two or more elements or compounds not chemically combined together.
