What type of water has the greatest density?

Density is measured as mass (g) per unit of volume (cm³). Water is densest at 3.98°C and is least dense at 0°C (freezing point). Water density changes with temperature and salinity….Water at:

What type of salt water has the greatest density?

In this manner, very dense seawater that is both cold and of elevated salinity is formed. Such areas as the Weddell Sea in Antarctica produce the densest water of the oceans. This water, known as Antarctic Bottom Water, sinks to the deepest depths of the oceans.

What is the least dense form of water?

water vapor

At what temperature water is most dense?

about 39°F

Which gas has maximum density?

The density of gases depends upon the temperature. The higher the temperature, the more the molecules are spread out and the lower the density as shown in the graphic on the left….

Can the density of a gas change?

Gas density is a function of the pressure and temperature conditions for the gas. Due to its high compressibility, gas can change its volume significantly with change in pressure. Therefore, density changes (at low pressure) can be significant.

Is density of gas constant?

This allows us to define a single additional property called the gas density r, which is the ratio of mass to volume. If the mass and temperature are held constant, the product of the pressure and volume are observed to be nearly constant for a real gas.

How do you find density of gas?

We know everything we need to find the volume now except the number of moles of gas. To find this, remember the relationship between number of moles and mass. But density is m/V, so flip the equation over to get: m/V = (MMP)/(RT) = density of the gas.
