Add more salt if the egg is still at the bottom.The science behind it:Things go down in the water when they are denser (更稠密) than the water. By adding salt we make the water denser. Once the water is denser than the egg. it goes up.You can also try other things to see if ...
Since DCE is denser than water, the DCE phase remains at the bottom of the vial, while the aqueous phase stays at the top. Within a minute of contact between the two phases, the aqueous phase, initially having a yellow color due to the chloroaurate ion, starts to lose its color and ...

In fact, superhydrophilic/superoleophobic oil–water separators are favorable com- pared to more traditional superhydrophobic/superoleophilic separators as water is denser than oil and tends to sink to the bottom of a mixture. Additionally, oleophilic separators or absorbent materials can quickly become...
These landslides caused warm, shallow water to become denser and flow downhill along the Cascadia margin following the 8.6 magnitude Indian Ocean earthquake on April 11, 2012, causing the temperature spikes. The Cascadia margin runs for more than 1,100 kilometers, or 684 miles, off the Pacific...
The experiment reveals a new mode of skipping, “water walking”, which is observed for relatively soft spheres impacting at low impact angles. The mode occurs when the sphere gains significant angular velocity over the first several impacts, causing the sphere to maintain a deformed, oblong ...

An analysis of historical data reveals that WTOW has been present in all but eight of the last 31 years at 57.5°N in the Rockall Trough. A denser component of WTOW below 1500 m has also been present, although it appears to be less persistent (12 out of the 31 years) and limited ...
In storage-type gas/oil water heater, cold water is supplied to the tank and injected at its bottom through a dip tube. The denser cold water is heated by a gas/oil burner. As the water heats up, it naturally rises and is drawn off by a hot-water discharge pipe. 2.2.2 Advantages ...
Preferably the polar solvent is denser than water and preferably the stripper composition has a diffusion rate through the cured finish greater than about 7×10 −7 g/cm 2 /sec. Strippable floor finish kits can be manufactured by combining a UV curable floor finish composition and an ...
