A crystal is a form of solid where the atoms are arranged in a predictable, specific pattern. Not all substances can form crystals because they're very delicate and specific. The atoms in a crystal form a repeating pattern called a crystal lattice. Examples: Diamond, Table Salt and ...
Gasoline is known as analiphatic hydrocarbon. In other words, gasoline is made up of molecules composed of nothing but hydrogen and carbon arranged in chains. Gasoline molecules have from seven to 11 carbons in each chain. Here are some common configurations: H H H H H H H | | ...
What Colors Are Found in Fires? Typically, fires can display a range of colors from soft blue and bright yellow to deep orange and rich red. Here's what the colors typically mean. Blue indicates a hotter, more oxygen-rich burn, often seen where the gas mix is optimal, such as in a ...
In what way are liquid and electrical circuit analogous? What is internal energy? How is internal energy of a real gas different from that of ideal gas? How does the arrangement of atoms in a crystalline substance differ from that in non-crystalline substance? How does the arrangement of atom...
Generally, that means that 37 billion atoms in the sample are decaying and emitting a particle of nuclear radiation (such as an alpha particle) per second. One gram of of the element radium generates approximately 1 curie of activity (Marie Curie, the woman after whom the curie is named, ...
There are many processes and phases involved in gasoline production and its subsequent delivery to gas stations. For this reason, theU.S. Energy Information Administrationdoesn’t attempt to pinpoint where fuel from local gas stations originates. Generally, it begins as crude oil within a petroleu...
For example, octane has a molecular composition of C8 H18, so there are 8 atoms of carbon and 18 atoms of hydrogen, so we have α=8, β=18, γ=0, and δ=0. Other fuel molecules have other compositions, obviously. Normally, chemists work with a quantity called a "mole", which ...
Then, through a process similar to a neon sign, they collide with the atoms and molecules of Earth’s atmosphere to create the light we call the aurora. Not all solar storms produce aurora. Only if the solar storm’s magnetic field couples with Earth’s magnetic field do we have a ...
The heating coil is simply a length of steel tubing arranged in a coil around the burner. When the balloonist starts up the burner, the propane flows out in liquid form and is ignited by a pilot light. As the flame burns, it heats up the metal in the surrounding tubing. When the ...
Wherever a photon of light hits, electrons are emitted from the photoconductive atoms in the drum and neutralize the positive charges above. Dark areas on the original (such as pictures or text) do not reflect light onto the drum, leaving regions of positive charges on the drum's surface....
