PLEASE HELP A student labels two 250 milliliter beakers with the letters A and B. She puts 100 milliliters of water in each of them. She adds some salt to beaker A and stirs until the salt dissolves completely. Then she adds another 50 milliliters of water to beaker A. She adds more salt to beaker B, and the salt in beaker B doesn't completely dissolve in the water even after much stirring. The solution in beaker A is The solution In beaker B is ​

Solution B is saturated and solution A is unsaturated

Explanation:

Saturated solution contains the maximum concentration of a solute dissolved in the solvent (usually water) and if extra solute is added to saturated solution, that solute will not dissolve.

Unsaturated solution means that more of a substance can be dissolved (in this example salt).

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
