Greatest to least 56.2,56.32,56.321

56.321 > 56.32 > 56.2.

Explanation:

A number line is the straight line in which number is represented along a straight line in a fixed interval. A number line can be extended infinitely and it can be extended in either negative direction or in positive direction.

In the given situation when we represent 56.2, 56.32, and 56.321 on the number line the number 56.2 lies on the left most side then 56.32 and after that number 56.321 lies means it is the order of increasing magnitude.

Therefore the pattern from the greatest to least lies as 56.321 > 56.32 > 56.2.

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
