Want this question answered?
With the lack of specific conditions, all I can say is this. If it is a cube for use in soup bases, it depends on the temperatuure of the water you drop it in and the amount of agitation it will experience while dissolving.
solute, solvent
Dissolving salt, or any other material for that matter, into water both lowers the freezing point, and raises the boiling point of water. So in the case of ice water, it would allow the water to be chilled below 0C (32F) while remaining a liquid.
Sugar dissolves very well in water (>65%) while starch only 'absorbs' water (slimy starch or glue) whithout dissolving. Cellulose (paper, cotton) is insoluble.
Salt water is a homogeneous solution as far as the salt is solubilized
The independent variables are the milk and water, while the dependent variables are the plants, because they don't change.

Dissolving salt into water is a physical change because no chemical reaction takes place, while the state of matter of the salt changes.
Session Variables
Vinegar is basically a solution of acetic acid in water. Therefore acetic acid is the solute and water is the solvent. See this site for information about dissolving and solutions: http://www.bbc.co.uk/schools/ks3bitesize/science/chemistry/physical_changes_8.shtml
Coke is a more viscous liquid than water, this is because water consists of 1 element in liquid form, while coke has solid in it (for exapmle sugar), this prevents it from dissolving too quickly
solute, solvent
the value of variables is determined by the equation, discrete variables have absolute single value while the continuos have a range value

It is a substance that may cease to be a solid by dissolving into it's solvent. Polar substances dissolve in water; most organic substances may be dissolved in water; while inorganic substances may only be dissolved in inorganic solvents.
