Aquatic plants are able to survive at 0 degrees Celsius (the freezing point of water) due to several factors. One important factor is that water has a high heat capacity, which means it can absorb and hold a large amount of heat energy. This allows water to buffer temperature changes and maintain a relatively stable environment.
Additionally, the heat of fusion of water is also significant in this context. The heat of fusion refers to the amount of heat energy required for a substance to change from a solid to a liquid state without a change in temperature. In the case of water, this value is relatively high.
When the temperature drops to 0 degrees Celsius, water begins to freeze and turns into ice. However, unlike most substances, as water freezes, it undergoes expansion instead of contraction. This results in ice being less dense than liquid water, causing it to float on the surface.
This floating ice provides insulation to the underlying water, shielding it from extreme temperature drops. It acts as a protective layer, allowing the water below to remain in a liquid state and providing a stable habitat for aquatic plants and organisms to survive during cold seasons.
aquatic plants survive at 0 degree celcious because water has high heat of fusion, which allows ice to float?
