Final answer:

When heating the beakers with water and salt, the uncovered beaker will experience water evaporation, leaving salt residue. The covered beaker will show water condensation, preventing significant water loss.


Explanation:

Observations: When heating the beakers with water and salt, in the uncovered beaker (B) where salt was added, the water will evaporate, leaving salt residue behind. In the covered beaker (A), the evaporated water will condense back into liquid water due to the cooling effect of the cover, resulting in no net water loss.
