What is the pH scale?

Back

The pH scale measures how acidic or basic a solution is, ranging from 0 (acidic) to 14 (basic).

Front

What is the significance of water's high specific heat?

Back

Front

Explain the concept of density.

Back

Density is the mass per unit volume of a substance, often expressed in grams per cubic centimeter (g/cm³).

Front

What is the role of dissolved oxygen in water?

Back

Dissolved oxygen is essential for aquatic life, as it is required for respiration by fish and other organisms.
