Low viscosity
High specific heat capacity
High surface tension
High pH value
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The property of water that helps in moderating Earth's climate and maintaining a stable temperature in aquatic environments is its High specific heat capacity.
Water's high specific heat capacity means it can absorb or release large amounts of heat with only a small change in its own temperature.
This characteristic allows large bodies of water (like oceans) to act as heat reservoirs, absorbing significant solar energy during the day or warmer months and releasing it slowly at night or during colder months.
T hereby stabilizing global temperatures and prevents drastic temperature swings that would otherwise occur.
