Methyl Iodide is a chemical compound that is relatively volatile. It is commonly found in the form of a dense, colorless liquid. It is also known as iodomethane and has the chemical formula CH3I (one carbon atom with three hydrogen atoms and a single iodine atom connected to it). Methyl iodide is a naturally occurring …
Magnets are mainly characterized for having poles: if you put together poles of the same charge they repel and if you put together charges of different pole, they attract. A body will be under Magnetic Levitation when it floats due to that special repelling quality of the magnets, i.e. when the force generated by the …
Transconductance is a property of some electronic components and is also known as mutual conductance. It is the opposite of resistance. The measure of transconductance is the ratio of the electrical current change at an output port as compared to the voltage change at the input port. The measure of transconductance is commonly used in …
There are three stages to a thunderstorm’s life cycle: the cumulus stage, the mature stage, and the dissipation stage. When a thunderstorm begins to form, it does so at the cumulus stage. From there, the storm advances in severity until it reaches its peak at the mature stage and then begins to gradually die out …
Weather modification refers to willful manipulation of the climate or local weather. Research done in this field goes back to as far as the early 1940s when the US military experimented with cloud seeding to stimulate rain. Today, private corporations have joined the weather modification research effort to protect people, cities and assets from the …
Photoelectron spectroscopy is the study of energy and how it relates to matter in terms of absorption and production. Photoelectron spectroscopy observes both wavelengths and frequencies and is used to view the physical composition of chemicals and solids. It is used in both analytical and physical chemistry and astronomy in order to study an object’s …
Blackbody radiation refers to the electromagnetic radiation that a blackbody material expels. Blackbody materials are substances that absorb all electromagnetic radiation that comes in contact with it, including light and heat. While a perfect blackbody material does not exist in nature, substances such as ash, soot, and granite come close. When a blackbody material is …
No one person invented electricity, but its modern day use is the result of the work of inventors, scientists, and researchers who toiled over the subject for millennia. In order to fully understand electricity in our modern world, one has to first understand the pioneers who date back to as early as the ancient Greeks, …
Lemon juice has a natural pH of 2.0 and is naturally acidic. When mixed with vitamins and other additives in the lemon juice normally found in stores for human consumption, the pH is slightly less acidic with a pH measure of between 2.2 and 3.0. Due to the natural acidicy of lemon juice, it can …
A fuel cell is a device that produces electrical energy through chemical reaction. This energy conversion process is known as electro-chemical energy conversion. The simplest form of electrochemical device that we use in our day to day life is a battery cell. A fuel cell is different from a battery cell in so far as …
