Which of the following are the consequences of the anomalous expansion of water?
Which of the following are the consequences of the anomalous expansion of water?
The correct options are
A Bursting of plant’s capillaries during winter
B Bursting of water pipe’s during winter
C It helps in preserving the aquatic life during the very cold weather
1. In winter nights, when the temperature starts falling below 4 ∘C, water in pipelines expands and it exerts large pressure on the pipes, causing them to burst.
2. Plants also die for the same reason as their capillaries burst when water expands below 4 ∘C.
3. In cold countries and Polar Regions during winter, the temperature goes below 0 ∘C. In lakes and ponds when water at the surface reaches 4 ∘C, it is densest and goes to the bottom. When the temperature further reduces, only surface layers of water freeze whereas at the bottom water remains at 4 ∘C. Aquatic animals live comfortably in water at 4 ∘C ,whereas, outside temperatures may go much less than that.
