Water and ether are placed on the palms of both the hands which will cause more cooling ether or water?

Ether has a greater cooling effect than water when smeared on your hands because of its evaporation method. Ether gets its energy from your hands. So when it evaporates, the cooling effect is greater than water.

Why does the water freeze when a beaker of ether is placed over the water?
Because ether is much more volatile than water and evaporates extremely quickly. As ether evaporates very quickly its average kinetic energy is lowered as molecules of ether escape. Following on, the 2nd law of Thermodynamics (I think) states that thermal energy is lost to cooler things so the water cools down extremely quickly as it looses heat to the evaporating ether which is also loosing heat in evaporation. Once the water reaches 0 degrees C it freezes.
Why is dimethyl ether soluble in water but pentane is not?
The oxygen in the dimethyl ether gives it more polarity than pentane; thus making it soluble in water
Is picric acid more soluble in water or ether?
In ether. However the difference is not so significant. The solubility of the commercially sold sample (%100 pure) in water is reported as 1g/65 ml. and in ether as 1g/78 ml. They account for 15.4 g/L water and 12.8 g/L ether. You can check out such properties of materials here:
why is it that sodium chloride is insoluble in ether?
Ether has a lower dielectric constant than water. Therefore, the energy required to separate the cations from the anions in ether is greater than in water. The entropy gain that could result from converting solid salt to a solution is therefore not great enough to overcome the attractions between the ions in ether, but it is great enough in water.
In the cannizzaro reaction why does the acid appear in the aqueous layer and the alcohol in the ether layer?
Because acid dissolves in water and alcohol dissolves in ether
Which causes more cooling ether or water?
Assume question is about evaporative cooling rate Ether had vapour pressure of around 0.7 ATM it would be readily evaporate in air. The ether would be a lot colder than water and cause higher cooling rate. However, if the matter talk about conduction cooling or cooling per unit mass it might be different answer from above.
Why does salt soluble in water not in ether?
Water is a polar liquid; ether is not.

Solubility of pb with lipids?
The lipid glycerol is soluble in both water and ether. Olive oil is soluble in ether, but not water. A solid lipid is insoluble in water, methanol, and ether.
How the vapour pressure of ether is greater than the vapour pressure of water?
Water molecules are held together by hydrogen bonds which are relatively strong. Ether molecules do not have such intermolecular forces holding molecules together. Therefore, it is easier for ether molecules to escape as a vapor, and this is why the vapor pressure of ether is greater than that of water.
Why is dimethyl ether soluble in water but pentane is not?
The oxygen in the dimethyl ether gives it more polarity than pentane; thus making it soluble in water
Where does ether exert its effects on nerve activity?
Ether will impair the function of the nerves. It does not leave any permanent damage, however. Ether anesthetic may cause side effects such as nausea.

Is water denser than ether?
Yes, water is denser than ether. Water has a higher density than ether due to the molecular composition of water being more tightly packed compared to the molecules in ether.
Why is tert-butyl methyl ether more polar than petroleum ether?
Tert-butyl methyl ether more polar than petroleum ethere cause petroleum ether isn't an ether- it's composed of hydrocarbons, which are nonpolar. The real ether that is in tBME includes oxygen, which is electronegative and creates more polarity in the molecule.
Why is naphthalene more soluble in petroleum ether than in water?
naphthalene is non-polar and can only dissolve in non-polar solvents. ether is non-polar, water is polar.
