Is there any differences in the experimental density and true density of water?

Question

if the experimental density of water is 0.974g/ml.
Give possible reason/s for their similarity and difference.

Answer 1

The density of liquid water, while close to 1g/ml, is actually variant with temperature. A lower density, such as .974 g/ml, would probably be due to warm or hot water.

Answer 2

The density of water is dependent on the temperature. In general, it decreases as the temperature increases. This behavior is not followed at temperatures close to zero degrees centigrade. (note: ice, which is solid water floats on liquid water).

Thus, it depends on the temperature when you did your experiment. Compare it with published standard values if your data is very close. The density of water is not always exactly 1.000 g/ml. Although your value may be a little off, that is exactly why it is called an experimental value. The published standard values are values that have been reproduced so many times by very controlled experiments using more precise instruments under controlled laboratory conditions.

There are also the usual reasons for differences. For instance, experimenter error, limits of instrument accuracy in measuring either the mass or volume or both, purity of water (Did you use TAP water?) etc.

Answer 3

Ice floats meaning the density is less than water for the iceberg to float. Ice is water which has frozed. So depending on the temperature of the water, marginal differences in density appear.

Answer 4

^^^sturdy Grief^^^ An plane in basic terms travels with the aid of air. Sonic growth happens at Mach a million ,761 MPH on an time-honored day 15C/59F. It gets less warm as you circulate up so it is going to decelerate somewhat until the temp stops reducing at 36,000 ft.

Answer 5

it is my understanding, ( if I remember right)

that the densest water is 4 degrees centigrage
warmer it expands, and colder is expands


now, if you were planning an expirment with water, you are most likely using room temp water, not 4 degree water,
so you would plan for the denisity at that temp, not at its densest temp.

Answer 6

Another possibility is miscalibrated measuring devices.
