With decreasing electrolyte concentration, either the needed voltage raises at constant current, either the passing current decreases at the constant voltage. Both happens because at lower concentration, a higher potential gradient across the electrolyte is needed to maintain the same current, as the smaller ion count requires ions to move faster for the ...

The heat transfer is limited by the flask material heat transfer rate, which is proportional to the thermal gradient within the flask. The external flask temperature will follow. On the water side, liquid can jump out of flask in form of the thick foam, powered by the vapour. This is the major limiting factor. On external side, at high enough power, the ...

Cetyltrimethylammonium bromide (CTAB) and its cheaper chloro homologue are just two examples of cationic detergents commercially available and frequently used e.g., for hair shampoos. They are called cationic because beside lipophilic alkyl groups their head group is positively charged: (source) Note, there equally are anionic and nonionc detergents, too. ...

Surprisingly enough, hemihydrate reacts quickly with water to produce dehydrate (gypsum). It is due to the fact that hemihydrate is produced by heating gypsum to a high temperature. This heating produces a structure with plenty of holes or voids corresponding to the previous positions of the water molecules. Water molecules can easily fill these holes if ...

in the sun hydrogen is in the plasma state, which makes it impossible to form bonds (because in the plasma state electrons are separated from the nucleus) not to mention the heat alone would easily break the bonds between hydrogen and oxygen if you brought water to the sun
