Answer 1

Answer:

1. Combination of different materials are Known as mixture
2. A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture. The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample. ... One characteristic of mixtures is that they can be separated into their components.
3. A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture. ... A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers. Each of the layers is called a phase.
4. To sublimate is to change the form, but not the essence. Physically speaking, it means to transform solid to vapor; psychologically, it means changing the outlet, or means, of expression from something base and inappropriate to something more positive or acceptable.
