Question

1.What is the true density of water? 2.What variables change the density of water? 3. How does water go against the concept of "Thermal Expansion"? Use full sentences that awnser the question? The response should be Fullllllll....... no copying from internet!!!!​

Answer 1

Answer:

1. A common unit of measurement for

water's density is gram per milliliter

(1 g/ml) or 1 gram per cubic

centimeter (1 g/cm3). 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).

2. Water density changes with

temperature and salinity. Density is

measured as mass (g) per unit of

volume (cm). Water is densest at

3.98°C and is least dense at 0°C

(freezing point). Water density

changes with temperature and

salinity.

3. When water is a liquid, the water

molecules are packed relatively

close together but can slide past

each other and move around freely

(as stated earlier, that makes it a

liquid). Pure water has a density of

1.000 g/cm3 at 4° C. As the

temperature increases or decreases

from 4° C, the density of water

decreases.

Answer 2

1. What is the true density of water?  

The true density of water is 1 g/cm³. (Actually, the exact density if water is not really 1 g/cm³, but a bit less (very, very little less), at 0.9998395 g/mol at 40 degree Celsius)

2. What variables change the density of water?

Temperature and purity can change the density of water.

3. How does water go against the concept of "Thermal Expansion"?

When water is a liquid, the water molecules are packed relatively close together but can slide past each other and move around freely(as stated earlier, that makes it a liquid). As the temperature increases or decreases from 4 degree Celsius, the density of water decreases.
