Question

Which separation procedure is most likely to happen? Freezing a compound will break it down into elements. Filtering a mixture will separate it into substances. Boiling a pure substance will separate it into mixtures. Melting an element will break it down into compounds.

Answer 1

The separation procedure involves the separation of mixture of compounds into the respective compounds.

Freezing is a process in which change of state takes place that is the substance in liquid state will change to solid state.

The process of separating solid particles from the liquid or gas by passing through the porous medium like filter paper allowing the liquid to pass through and retains the solid is said to be filtration.

The temperature at which the vapor pressure and atmospheric pressure becomes equal is said to be the boiling point of the substance.

Melting is a process in which change of state takes place that is the substance in solid state will change to liquid state.

Thus, for separation procedure filtering a mixture will separate it into substances.

Answer 2

Answer is: Filtering a mixture will separate it into substances.

Pure substance is made of only one type of atom (element) or only one type of molecule, it has definite and constant composition with distinct chemical properties. Pure substances can be separated chemically, not physically, that is difference between pure substances and mixtures.

Filtration is use for separation of heterogenous mixture, for example, sand and water.
