Question

when water freezes at 0c its density decreases due to

Answer 1

Answer:

Ice

Explanation:

Due to empty space present in the structure of ice

Answer 2

The empty space is present in the structure of ice.

• When water freezes at 0c its density decrease due to the empty space in the structure of ice.
• The density of water increases as it is cooled, but at 4°C, it reaches its maximum density.
• After that density decreases when it approaches the freezing point. It decreases due to the empty space present in the structure of ice. This property of water is essential for aquatic life.

• When water is cooled from a higher temperature, it also contracts,i.e. decreases in volume till it reaches 4 degrees Celsius ( 39.2 F ). When cooled from 4 C to 0 C ( 39.2 to 32 F ), it behaves differently than other materials and expands ( volume increases ).
• So, the density of water decreases. So, the density of water at the freezing point, i.e. density of ice is less than water. Volume decreased when you cooled it to 4 C, then increased when further cooled to 0 C. So, the minimum volume is at 4 C, so the density of water is maximum at 4 C.
