Question

water has minimum volume and maximum density at – 4 degree Celsius​

Answer 1

Answer:

Due to the anomalous expansion of water.

Explanation:

Lets assume water at room temp.(30°c).When Thai water is cooled it's temp. goes down. When it reaches 4°c its molecules compress hence more density and less volume at 4°c and when it reaches 0°c on further cooling it forms ice which has less density and more volume because it's molecules expand below 4°c.

Answer 2

Answer:

• At 4C, water exhibit maximum density and minimum volume. On further cooling down, water expands and the density of water decreases from 4C to 0C.
