Substance A and substance B are mixed together. To separate the mixture, water is added, and substance A is filtered out. Then,
Sveta_85 [38]

The correct answer would be that substance A is rice, and substance B is sugar.

For substance A to be filtered out, it means that A is a water-insoluble substance and for substance B to be recoverable by evaporating off the water, it means that B is water-soluble.

Thus, A can neither be sugar nor alcohol because neither can be recovered by filtration. Also, B can neither be coffee nor alcohol because they can not be recovered as residue through evaporation of water.

Therefore, the only correct answer is that substance A is rice, and substance B is sugar because rice can be filtered out from water while the water-soluble sugar can be recovered by evaporating the water.
