Warm water holds _____ oxygen than cold water.

Warm water holds less oxygen than cold water due to several key physical principles related to gas solubility. The solubility of gases in liquids generally decreases as temperature increases; this means that as water gets warmer, its capacity to hold dissolved oxygen diminishes.

This phenomenon can be attributed to the kinetic energy of the water molecules. In warmer water, the molecules are more energized and move more vigorously, making it harder for gas molecules, like oxygen, to remain dissolved. As a result, the increased kinetic activity in warm water leads to a reduced ability for oxygen to stay in solution.

Conversely, cold water molecules have lower energy and movement, allowing gas molecules to be trapped more effectively within the liquid. This is why aquatic environments that are cooler typically contain higher concentrations of dissolved oxygen, which is crucial for the survival of many aquatic organisms.

The other options do not align with this established scientific principle regarding temperature and solubility.
