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...
The hydro- gen molecules split into electrons and protons at the anode 4 . The protons 5 migrate through the membrane to the cathode 6 . The electrons 7 flow through an external conductor to the cathode, providing electricity along the way. At the cathode, oxygen molecules react with the ...
however, fast internet on the plane has failed due to the lacking capacity of data connections between the plane and the ground. For the first time, a team of researchers at Karlsruhe
Free radicals are 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...
Things are really quieting down on planet Earth. Credit: The Royal Observatory of Belgium. As COVID-19 continues to wreak its viral havoc on the human population of Earth, governments around the world have closed their schools, shut down non-essential businesses, and told their citizens to st...
Since the long chain hyaluronic acid molecules in synovial fluid are discovered as additive, this theory states that fluids with very large molecules exhibit noticeable magnitudes of Couple-stress [16,17,18,19,20,21,22]. In recent years, there has been a lot of interest in figuring out how...

The velocity of gas molecules emerging from the warm end of the particles is higher than that of those emerging from the cold end. Collision of the molecules with the particles occurs quite vigorously, as they move more quickly. Because of the discrepancy in momentum, the particles develop a ...
