Because the density of the egg is higher than the density of tap water, so it sinks.

When the aluminum ball had a diameter of 6.0 cm, the ball should have floated well because it had a density lower than that of water due to the air inside of the ball, just like steel ships that can float because their density has been lowered by encasing air inside the hull.

With a diameter of about 1.6 cm or smaller, the ball should have completely sank, indicating that its density was greater than that of water, thereby overcoming the buoyant force.

Travelling between the stars for a hundred light years or so, we would find ourselves moving between regions where the density of gas changes a millionfold — more extreme than the difference between air and water — and with changes in temperature from just a few degrees above absolute zero to over a million degrees.

Because water has greater density than air and flows are more constant than wind, underwater turbines can deliver much more energy than wind turbines.

Although artificial - muscle technology can weigh significantly less than comparable electric motors — the polymers themselves have the density of water — efforts are ongoing at SRI to cut their mass by reducing the need for the external structure that prestrains the polymers.

Affluent neighborhoods with lawns — and occasionally swimming pools — use up to 10 times more water than neighborhoods with higher density housing with less landscaping, according to a Portland State University study.

Remote - sensing devices that are sensitive to minute variations in the water content of soil revealed the footprints of vanished houses, water tanks, canals, and even historic rice fields, leading researchers to conclude that Angkor is most likely the world's largest archaeological site, a sprawling low - density metropolis covering an area larger than New York City.

Studies of anomalies in water's behavior have indicated the existence of liquid water with both lower and higher densities than this standard.

The final stage of this kind of low - mass star is typically a ball not much larger than Earth but with a density perhaps 50,000 times that of water.

Its high salt content increases the water's density, which is why people float in the Dead Sea more easily than in the ocean.

A new study on the density of the seven planets in the nearby TRAPPIST - 1 system has found that these worlds may have even more water than Earth does — but in a cruel case of having too much of a good thing, that might be enough to drown out any hopes of finding life there.

The planets» densities, now known much more precisely than before, suggest that some of them could have up to 5 percent of their mass in the form of water — about 250 times more than Earth's oceans.

Some may be composed entirely of water; others have densities greater than iron or lower than Styrofoam.

Because water has much greater density and resistance than air, you will get a great resistance workout as well.

Fact: water is a standard for weight, volume & density — anything heavier or more dense than water will sink in water.

When the sea - ice forms, the freezing process rejects brine, which has a higher density than the surface waters and which sinks to the continental shelf.

Yes when fresh water ice melts in fresh water the water level doe snot change but I was referring to the oceans and they contain sea water of higher density than fresh water.

This may be me advertising my ignorance but if the OHC is of interest as against the SST why do we use a parameter of «global temperature» which is an amalgam of SST and air temperature over land rather than a total heat content or a temperature normalised say for mass or thermal density (normalise to the properties of water say)?

Another study found that average soil water content on low density ponderosa forests (250 trees / ha) was substantially higher than on high density forests (2,710 trees / ha), although these differences in forest density were not a result of mechanical thinning [58].

A point is reached where the density of the cooling surface water becomes greater than the density of the deep water, and overturning begins as the dense surface water moves down under the influence of gravity.

Everything else being equal, warm water has a lower density than cold water and won't sink into the deep cold oceans.

Their hope (claim) is that there can be occasions when salinity, rather than temperature, is the prime determining factor in the density of the surface waters.

The moons small density will have an effect on the surface of the planet as water is denser than land and has elasticity to it.

When dipped into a beaker of water, instead of producing electricity, the leaf harnessed the electrons to break the chemical bonds of water and release hydrogen gas — a fuel that can store energy at a significantly higher density and lower cost than electricity.

Adding the influence of water vapor concentration to the density profile makes the difference between the densities of the two cases a little larger, because water vapor lowers the density as H2O molecules are lighter than average for dry air.

It seems to make a clear enough statement, that if you can make dry air move down a density gradient, then water (why water rather than some other liquid?)

For sinking of a parcel to occur, its mass density MUST be lower than that of the surrounding waters.

@CH: I have nothing against Arcimeded, although it seems that your original proposition is not strictly true if the density of the object is greater than water.

The trees were able to endure such low water potentials and maintain basal levels of metabolism because ecological forcings kept the tree density and leaf area index of the woodland low, physiological factors forced the stomata to close progressively and the trees were able to tap deeper water sources (below 0.6 m) than the grasses.

Wave energy is alluring because, due to water's density, waves and tides can easily generate more electricity than renewables such as wind and solar power.

I have no concept of how often a photon will «tip» a molecule to evaporate, but I don't think it's a high proportion because one thing I do have a concept of is that the density of photons in a 400W / m2 beam of DLR is far greater than the number of water molecules capable of absorbing that DLR.

Only if the oceans freeze across their entire surfaces thereby causing the hydrological cycle to cease or if the sun puts in energy faster than it can be pumped upward by the hydrological cycle will the basic temperature equilibrium derived from the properties of water and the density and pressure of the atmosphere fail to be maintained.

Micro bubbles found in deep polar ice cores of the ancient atmosphere (1 - 200,000 years ago) showed a higher atmospheric density than now, perhaps 2 atmospheres, also higher water vapor and CO2.

At some point increasing density must lead to descending fingers of saline water which could be warmer than the surroundings, thus transferring heat to depth.
