The carbon and hydrogen combine with oxygen from the air to make carbon dioxide gas and water, while the energy that held the molecules together is released as heat. This process, which is called combustion, releases huge amounts of energy. When you sit round a camp fire, warming yourself ...
Why are temperatures on the gas giants so low? Why can't cold-blooded animals produce heat? Why does metal lose magnetism when heated? Why is heat absorbed in glass transition? How does increased heat affect the states of matter? Why is a sunset red in terms of ph...
how fast or slow molecules are moving. When molecules move faster, the temperature increases. Measured with a thermometer. Is measured in °F, °C, or K. Wind • What is wind? - A measurement of how fast the air is blowing and in what ...
How fast the alcohol is absorbed depends upon several things: The biological sex of the drinker. Alcohol is metabolized differently in women and men, due to factors like body composition. The concentration of alcohol in the beverage. The greater the concentration, the faster the absorption. The ...
The direction and speed of pH change depends on the mechanism by which FAs move across the bilayer. Using BCECF to monitor each change, we predict that the cotransport of FAs and H+ through a transport protein would produce a slow pH drop which could be inhibited (red star) (A) or the...
that the system can only evolve in specific (and most importantly, continuous) ways between those points, and in such a way that the rate doesn't matter (expanding a volume of gas in a perfectly insulating cylinder, changes its temperature adiabatically, no matter how fast ...
Why do the energetics (heat flow and work) of fast and slow processes differ? How does rotogravure printing work? Why is water used in offset printing? Why does water heat up and cool down slowly? Why is offset printing utilized? Why is a warm combustion e...

This geological process created complex molecules of hydrogen and carbon. Oil can also contain other elements. Crude oil, or unprocessed petroleum, is called sour when it contains a lot of sulfur, an impurity. Sour crude requires more refining than sweet crude, which is often more valuable. ...
Cells in simulated microgravity undergo a reversible morphology switch, causing the appearance of two distinct phenotypes. Despite the dramatic splitting into an adherent-fusiform and a floating-spherical population, when looking at the gene-expression p
