The density of solids and liquids normally increases with decreasing temperature. (Figure) shows the density of water in various phases and temperatures. The density of water increases with decreasing temperature, reaching a maximum at 4.0°C, and then decreases as the temperature falls below 4.0°C.

Change of Temperature and Pressure affecting Fluid Density
Changing the temperature and pressure of a fluid can have a significant impact on its density. Let's break down how each factor influences the density of a fluid:
Change of Temperature:
- As the temperature of a fluid increases, the molecules within the fluid gain energy and move more rapidly. This increased movement causes the molecules to spread out, leading to a decrease in density.
- Conversely, when the temperature decreases, the molecules lose energy and move more slowly, resulting in a closer packing of molecules and an increase in density.
Change of Pressure:
- When the pressure on a fluid is increased, the molecules are forced closer together, leading to a higher density.
- On the other hand, reducing the pressure allows the molecules to move further apart, resulting in a lower density.
Combined Effect of Temperature and Pressure:
- The combined effect of temperature and pressure on fluid density is intricate. Changes in both temperature and pressure can work together to either increase or decrease the density of a fluid.
- For example, if the temperature of a fluid increases while the pressure decreases, the overall effect on density will depend on the relative magnitude of each change.
In conclusion, the density of a fluid is affected by both temperature and pressure. Understanding how these factors interact is crucial in various fields such as physics, chemistry, and engineering.
