Bulldozer is a kind of construction equipment using track-type tractors/chain and is equipped with a blade that lies ahead. Lightning is a natural phenomenon that typically appears during the rainy season when the sky bring momentary blinding flash of light. Oxygen is a chemical element in the periodic table systems that have a symbol O and atomic number 8. Who will win?

In addition to a blade as standard equipment Bulldozer, on the back side of the Bulldozer could be installed additional equipment in the form of:
- Ripper to unload material that can not be excavated using a blade, usually for road construction or mining work.
- Winch to pull the material, often used in work expenditures wood in the forest.
Generally bulldozer is widely used in mining jobs, especially for coal mining. Bulldozer is used for leveling the ground, dig and uproot trees during the process of land clearing.
Lightning |
Lightning is a natural phenomenon that can be our analogy with a giant condenser, where the first plate is the cloud (negative plate or plates can be positive) and the second plate is the earth (considered neutral). As already known capacitor is a passive component in an electric circuit that can store energy for a moment (energy storage). Lightning also can occur from cloud to cloud (intercloud), where a cloud of negatively charged and the other positively charged cloud.
Lightning occurs because there is a potential difference between cloud and earth or with other clouds. The process of charge on the cloud as it moves continuously on a regular basis, and during the movement he will interact with other cloud so that the negative charge will gather on one side (top or bottom), while the positive charge gathered on the reverse side. If the potential difference between the cloud and the earth large enough, it will happen disposal negative charge (electrons) from cloud to earth or vice versa to reach equilibrium. In the process of disposal of this charge, the media through which the electron is air. At the time of the electrons can penetrate the air isolation threshold is an explosion of sound. Lightning is more common in the rainy season, because in these circumstances the air contains higher water levels so that power down insulation and current flows more easily. Because there is a cloud of negatively charged and positively charged clouds, then lightning could also occur between different cloud charge.
Oxygen |
At standard temperature and pressure, oxygen gas in the form of a colorless and odorless with a chemical formula O2, where two oxygen atoms chemically bonded to spin triplet electron configuration. This bond has a bond order of two, and is often described simply as a double bond or as a combination of the two-electron bond with two three-electron bonding.
In normal triplet form, O2 molecules are paramagnetic because of the spin magnetic moment of the unpaired electrons of the molecule and the negative exchange energy between neighboring O2 molecules. Liquid oxygen will be attracted to the magnet, sedemikiannya on laboratory experiments, liquid oxygen bridge will be formed between the two poles of a strong magnet.
