Why water has maximum density at 4 degree Celsius explain?

As the temperature of warm water decreases, the water molecules slow down and the density increases. At 4 °C, the clusters start forming. The molecules are still slowing down and coming closer together, but the formation of clusters makes the molecules be further apart. Thus, the density of water is a maximum at 4 °C.

What is the maximum density of water at 4 C?

Detailed Solution. The maximum density of water is 103 kg m-3 at 4oC temperature. The maximum water density occurs at 4°C, since two opposing effects are in equilibrium at this temperature. The water molecules in ice are in a crystal lattice that has plenty of empty space.

What happens to water density as temperature increases?

When the water is heated, it expands, increasing in volume. The warmer the water, the more space it takes up, and the lower its density. When comparing two samples of water with the same salinity, or mass, the water sample with the higher temperature will have a greater volume, and it will therefore be less dense.

At what degree Celsius does water reach its maximum density?

4 °C
Water. An especially notable irregular maximum density is that of water, which reaches a density peak at 4 °C (39 °F).

What is the density of water 4 degree?

Actually, the exact density of water is not really 1 g/ml, but rather a bit less (very, very little less), at 0.9998395 g/ml at 4.0° Celsius (39.2° Fahrenheit). The rounded value of 1 g/ml is what you’ll most often see, though.

At what temperature is the density of water greatest?

39°F
As water cools it becomes more dense. At 39°F (or 3.98°C to be exact) water is the most dense.

Which has a greater effect on density of water temperature or pressure How do you know?

The density of water increases as the salinity increases. The density of seawater (salinity greater than 24.7) increases as temperature decreases at all temperatures above the freezing point. The density of seawater is increased by increasing pressure.

When water freezes what happens to its density?

Ice is less dense than water This is due to ice’s density being less than liquid water’s density. Upon freezing, the density of ice decreases by about 9 percent.

How does the density of water change when it is heated from 4 degree Celsius to 10 degree Celsius?

(b) it is heated from 4°C to 10°C? Solution: (b) The density of water is maximum at 4°C. It decreases when it is cooled from 4°C to 0°C or it is heated above 4°C.
