The drawing of a liquid up the inside of a small-bore tube when adhesive forces exceed cohesive forces, or the depression of the surface of the liquid when cohesive forces exceed the adhesive forces.
- Chemical Safety
People use chemicals every day for a wide array of purposes, which can include work and house hold duties. Many of us fail to realize that we are actually handling potentially deadly chemicals when we simply clean the bathroom or wash the car. This brings to mind the reason why chemical safety is...
- Diamonds Are Forever
Diamonds are still a girl's best friend, right? We love the shiny gems. They are the most popular rocks sold today. But what exactly are they, anyway? Where do they come from? What else are they used for?
- What are Compound Microscopes?
Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...
- Harmful Chemicals Found In Food
It's getting close to New Years and many people are starting to think about how to lose those extra pounds they managed to gain over the holidays. There are many sorts of diets and fads that have developed over the years from cutting carbs to cutting protein. Everyone has their own opinion as to...
- What's In Your Beverage? How to Ensure Quality Control with CO2 Analytical Support
Calibration standards, performance audits, and the FDA's never-ending safety, labeling, and inspection requirements are just the tip of the iceberg when it comes to dealing with the increasingly stringent quality control standards of the beverage industry. As these quality standards become...
Secondary Voltaic Cells
Voltaic cells that can be recharged, original reactanats can be regenerated be reversing the direction of the current flow.
Lead Storage Battery
Secondary voltaic cell used in most automobiles.
Free Energy, Gibbs Free Energy
The thermodynamic state function of a system that indicates the amount of energy available for the system to do useful work at constant T and P.
Spontaneous decomposition of an atom.
A binary compound in which H is bonded to one or more of the more electronegative nonmetals.
A theory, that attempts to explain macroscopic observations on gases in microscopic observations on gases in microscopic observations on gases in microscopic or molecular terms.
Conjugate Acid-base Pair
In Bronsted-Lowry terminology, a reactant and product that differ by a proton, H+.
The liquid and solid phases, phases in which particles interact strongly.
Density is the ratio b/w Mass and Volume: D=M/V
A device for measuring pressure.
Method of dating ancient objects by determining the ratio of amounts of mother and daughter nuclides present in an object and relating the ratio to the object?s age via half-life calculations.
Descibes the quantitative (mass) relationships among elements in compounds.
A mixture which has uniform composition and properties throughout.
Reaction of a substance with water.
An atom in a molecule or polyatomic ion that is bonded to more than one other atom.
Equilibria involving species in more than one phase.
Symbol for an atom A/Z E, in which E is the symbol of an element, Z is its atomic number, and A is its mass number.
The rate at which a particular substance will vapourize (evaporate) when compared to the rate of a known substance such as ethyl ether. This term is especially useful for health and fire-hazard considerations.
Differential Scanning Calorimetry (DSC)
A technique for measuring the temperature, direction, and magnitude of thermal transitions in a sample material by heating/cooling and comparing the amount of energy required to maintain its rate of temperature increase or decrease with an inert reference material under similar conditions.
Bonding of atoms of the same element into chains or rings.
The bonding together of atoms of the same element to form chains.
The ability of an element to bond to itself.
