Melting/Freezing points and Boiling/Condensing points aren't just based on temperature; pressure is also involved. This fact can be observed by having a weighted wire go through a block of ice, as witnessed in this video.
As shown in the video, pressure is also a major factor in determining the melting point of ice. On a molecular level, the molecules under the wire get increased kinetic energy, causing them to become liquid. once the wire passes through that part of the block of ice, th
Substances are magnetized when their electrons spin in the same direction. What this does is it creates charge differences in a substance.
Magnets have north and south poles. These poles dictate the direction in which the magnetic field flows both inside and outside of a magnet. On the outside, field lines flow north to south; inside they flow south to north.
Interestingly enough, magnets will always have both a north and a south pole. This can be observed if a magnet is cut in half. Since
There are two often used ways of avoiding RADAR (RAdio Detection And Ranging): Stealth and Jamming.
My previous blog post covered stealth. This one will cover jamming.
World War Two era planes weren't equipped with stealth technology to avoid radar, because it didn't exist yet. The air forces of the world had to figure out ways to avoid radar, and thus they figured out how to jam radar.
World War Two era bombers were easily picked up by radar, so to confuse the towers, the planes releas
