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).

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
