3D render of blue colored hydrogen molecules.(7 pages)Fuel has always powered humankind’s technological advances, from the wood-burning fires first used to cook food to the fossil fuels that propelled the Indu
What causes an air mass to have a low pressure? What happens to molecules during evaporation? What happens after a stream's discharge increases? What happens to water at room temperature if you decrease the atmospheric pressure around it? How does gas exchange occur? Why does a hot air ballo...
Which substance would have the highest vapor pressure? a) CH3CH2CH2CH3 b) CH3CH2CH2CH2CH3 c) CH3CH2CH2CH2CH2CH3 d) CH3CH2CH2CH2CH2CH2CH3 e) The vapor pressure is about the same for all of the listed molecules. What is the relationship between the vapor pressure of a liquid and its bo...
Elmo's Fire is simply sparking, something like a shot of electrons into the air. It's a corona discharge, and it occurs when there is a significant imbalance in electrical charge, causing molecules to tear apart, sometimes resulting in a slight hissing sound. The first step in generating ...
The state of matter can be changed by heating or cooling it or by changing the pressure conditions on it. When a material changes state, its molecules behave differently but don't break apart. Since they remain essentially the same, they don't form a different material but simply change the...
It is the weight of air molecules pressing down on the Earth. The pressure changes as you move upward into the atmosphere. What causes lightning and what are the warning signs before lightning strikes? Find out on this fascinating page about lightning. ...
fertility has received widespread attention. A survey in multiple European countries showed that 38–58% of individuals who had planned to have a baby in 2020 were going to postpone this decision76, although expected financial challenges caused by the pandemic was the main reason for this choice....
It’s what happens when a burst of kinetic energy enters the air through which a planes flies. That energy in turn causes sudden, unpredictable changes in the pressure and velocity of a fluid. This is the result: Maybe the word “unpredictable” gives you pause, but why should a process ...
So if we have a gas moving from a larger diameter pipe to a smaller one, the gas molecules will actually be more spread out in the smaller diameter pipe (and thus the lower pressure)? Is it correct I think of this in terms of the following analogy? When there's a traffic jam...
Removing the applied electric field allows the electrons in the dielectric to return to their normal distribution around the nuclei to which they’re attached, or the molecules in the substance to return to their original random orientation or shape. In the process of so doing, most of the ...
