An object's state of matter as a solid, liquid, or gas is determined by how close its atoms are to one another. Explore the properties of the three states of matter and how particles of matter move in solids, liquids, and gases. ...
Liquids and gases are known as fluids. Fluids have various similarities and differences. Some of the basic properties of fluids are density, viscosity, temperature and pressure. In gases, the particles are moving in a random motion with high kinetic energy. In case of liquids, the kinetic energ...
aHowever, ionic liquids have great potential for biotransformations of highly polar substrates such as amines and carboxylic acids in our case. Although they are very polar, the ionic liquids do no inactivate the enzymes as would organic solvents of similar polarity or nucleophilicity(lower alcohols ...

Maybe when these guys go over, they don't form solid reaction products, maybe they're liquids, or maybe they’re gases - who knows. But then it wouldn't build up this film of reaction products that block the negative. So it's pretty mysterious. Here's a graph that kind of...
If one or more double bond is present, the fat is unsaturated. If only one double bond is present, the molecule is monounsaturated. The presence of two or more double bonds makes a fat polyunsaturated. Unsaturated fats are most often derived from plants. Many are liquids because the double ...
You'll see, liquids and gasses are a bit less likely than your first guesses seem to be. Note: once you have good instincts, you'll still find surprises, uranium hexafluoride is a gas, this allows us to isolate isotopes for weapons enrichment easier. There are advanced physical chemistry ...

It's easy to see how a world full of hydrogen cars might work. We'd have lots of electrolyzer factories all over the place making hydrogen gas from water. Now gases take up a vast amount more space than liquids or solids, so we'd need to turn the hydrogen gas into liquid hydrogen,...
water molecules form strong hydrogen bonds with one another, causing them to stick tightly to one another. Since the water molecules have very strong intermolecular forces with each other and interact only weakly with carbon tetrachloride (via London dispersion forces—seeLiquids and Intermolecular Force...
