Describe briefly how the volume of a given mass of water changes when it is cooled from 7 ^0 C to 1^0 C use the terms increase, decrease and maximum or minimum

When water is cooled from 7°C to 1°C, its volume undergoes a specific pattern of changes.

1. Initially, as the temperature decreases from 7°C, the volume of water decreases due to the contraction of the water molecules. This means that the volume decreases or becomes smaller.

2. At a specific temperature, called the temperature of maximum density, the water reaches its minimum volume. For pure water, this temperature is approximately 4°C. At this point, water has the highest density and occupies the least amount of space.

3. As the temperature continues to decrease below 4°C, the volume of water starts to increase. This happens because water molecules, due to hydrogen bonding, start to arrange in a more open structure as they approach the freezing point.

4. Finally, as the temperature reaches 1°C, the volume of water is greater than it was at 7°C, indicating an increase in volume.

In summary, the volume of a given mass of water decreases initially, reaches a minimum at the temperature of maximum density, and then increases again as it gets closer to the freezing point.

When water is cooled from 7°C to 1°C, its volume undergoes specific changes. To understand this, we need to know the behavior of water when it goes through temperature variations.

Water is unique compared to other substances because it expands as it cools down from 4°C to 0°C (freezing point). This behavior is opposite to what most substances display.

So, when water is cooled from 7°C to 1°C, it will experience an expansion in volume due to this property. More specifically:
- The volume of water will increase as it cools down from 7°C to 4°C.
- The volume will then decrease as it cools from 4°C to 0°C (the point of maximum density).
- Finally, the volume will decrease even further as it cools from 0°C to 1°C.

In summary, the volume of water will increase initially, but after reaching its maximum density at 4°C, it will decrease as it continues to cool down to 1°C.
