What Are the 4 Key Properties of Water? Explained Simply
Discover the 4 essential properties of water—cohesion, adhesion, high specific heat, and lower density as a solid—and their importance.

1. Cohesion: Water molecules attract each other, leading to surface tension. 2. Adhesion: Water molecules stick to other substances, aiding capillary action in plants. 3. High Specific Heat: Water can absorb a lot of heat before rising in temperature, helping regulate climate. 4. Lower Density as Solid: Ice floats on water because it is less dense, which insulates aquatic life in winter.
FAQs & Answers
- What causes water to have high surface tension? Water’s high surface tension is caused by cohesion, where water molecules attract each other strongly due to hydrogen bonding.
- How does adhesion help plants absorb water? Adhesion allows water molecules to stick to plant tissues, facilitating capillary action that helps water travel from roots to leaves.
- Why does ice float on water? Ice floats because solid water (ice) is less dense than liquid water, creating insulation that protects aquatic life in cold conditions.
- What is the significance of water’s high specific heat? Water's high specific heat means it can absorb a lot of heat without changing temperature quickly, helping stabilize climates and maintain life-supporting environments.
