Do moving molecules make things cool down? Adding energy (heating) atoms and molecules increases their motion, resulting in an increase in temperature. Removing energy (cooling) atoms andmolecules decreases their motion, resulting in a decrease in temperature. ... During conduction the slower-moving...

Free radicalsare incomplete molecules looking for an electron so they can complete and stabilize themselves. Sounds like something you’d hear in therapy. They steal an electron from a neighboring molecule, turning it into a free radical and setting off a chain reaction. They contribute to the ...
Density refers to how close together the molecules of an object are. For example, most rocks sink in water because they are denser than water. Also, the surface (i.e., the outside of an object) that touches the water displaces it, or pushes it out of the way. The shape of an ...

aEspecially fastness properties for unfinished leather are dominated by the used coloration technology. Conventional dyes for leather coloration are acid dyes which bind by means of ionic interaction. Negative charges in the dye molecules are attracted by positive countercharges in collagen created throu...
. (SeeMore Applications of Magnetism.) Historically, such techniques were employed in the first direct observations of electron charge and mass. Today, mass spectrometers (sometimes coupled with gas chromatographs) are used to determine the make-up and sequencing of large b...
The key, explained Blaga, is that during the brief span of time between when the electron is knocked out of the molecule and when it re-collides, the atoms in the molecules have moved. The LIED method can capture this movement, "similar to making a movie of the quantum world," he adde...
