Any residue present after evaporation of a solvent must have been either dissolved in the solvent, [by definition, permanently] suspended in the solvent, or a precipitate lying on the bottom of the solvent container, assuming that the solvent had not been disturbed for at least two hours.
Regulatory samples, such as environmental samples taken from a lake or river for analysis, are typically shaken or stirred immediately before being passed through a filter with a 100 to 200 micron (micrometer) pore size to catch any precipitated solids. Weighing the filter before and after it has been used and allowing it to thoroughly dry will yield the mass of any precipitated solids.
The first filtering is not always performed, and if it is, a filter with a larger pore size is sometimes used. These things depend on the specific procedure being followed and may also depend on whether there are any visible precipitated solids after the sample has been left undisturbed for several hours.
Assuming that no precipitated solids are present or that the sample is either centrifuged or allowed to settle before some of it is carefully decanted off for further analysis, the only way to distinguish the mass of any suspended solids vs. the mass of any dissolved solids is to pass the sample through a filter with a 0.45 micron, or smaller, pore size. A filter with that small of a pore size will capture virtually anything suspended in a solvent.
The mass of any suspended solids present may be determined by comparing the dried filter's mass before and after filtration. Comparing the mass of a sample dish containing an aliquot of the filtrate (the solvent that was filtered) before and after the solvent was allowed to completely evaporate allows the analyst to determine the percentage of dissolved solids.

What is the name of the solid trapped by filter paper?
It is sometimes called particulates, and after filtering the liquid is called the filtrate.
What is the name of the process of liquid turning into gas?
It is evaporation
What name is given to a solid recovered from a filtration?
The name given to a solid recovered from a filtration process is the "filtrate." This refers to the material that remains on the filter after the liquid component has passed through. The solid collected can vary in composition and is often further processed or analyzed depending on the specific application.

When water is added to the mixture potassium nitrate dissolves. The mixture is then filtered. The filtrate is potassium nitrate solution while the residue is a mixture of sulphur and charcoal. The filtrate is evaporated on a sand bath to obtain nitre back. When carbon disulphide is added to the residue, sulphur dissolves. When this mixture is filtered the filtrate is sulphur solution while the residue is charcoal. Leaving it open evaporates the sulphur solution. Carbon disulphide evaporates and sulphur crystals are left behind.

How do you compare and contrast evaporation and sublimation?
Evaporation is changing of liquid state into gaseous state. Sublimation is changing of solid state into gaseous state.
What is the name of the word when you turn a solid into a gas?
sublimation, evaporation without any noticeable melting, you can't see liquide
