the sugar, on the other hand, is dissolved, and its physical properties have changed. the sandwich whose ingredients or substances retain their physical properties, such as color, shape, and size, are called mixtures. in such mixtures, the substances are not evenly distributed and can be easily _. here are some examples of other heterogeneous mixtures. how are these mixtures separated? one way to separate sand and water is using _.

Explanation:

1. When a substance is dissolved, its physical properties change.
2. Mixtures where substances retain physical - properties are called heterogeneous mixtures.
3. In heterogeneous mixtures, substances are not evenly distributed and can be separated.
4. Sand and water (a heterogeneous mixture) can be separated by filtration as sand is insoluble in water and filtration can trap the sand while allowing water to pass through.

Answer:

1. changed
2. heterogeneous mixtures
3. separated
