Practical Chemistry

It is a collection of experiments that demonstrate a wide range of chemical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Chemistry is a practical science. The Photographic Periodic Table of the Elements.

Amusement Park Physics

You will be building a conceptual coaster using the physics concepts that are used to design real coasters. You won't need to compute any formulas. You will decide the following - the height of the first hill, the shape of the first hill, the exit path, the height of the second hill, and the loop. Fysikaliska Leksaker.

History of the Periodic Table

Dmitri Mendeleev Created the Periodic Table That We Still Use Today © The Regents of the University of California, Lawrence Berkeley National Laboratory, 2010. View More Figure 4-2. Dmitri Mendeleev Created the Periodic Table That We Still Use Today Born in Siberia, Russia, Mendeleev was the youngest of 14 children. Periodic table activity. The Compound Interest Periodic Table of Data. Today’s graphic is one that I’ve been working on over the past couple of weeks.

The Compound Interest Periodic Table of Data

Every chemistry classroom has a Periodic Table, but it’s often a drab affair; considering it’s one of the cornerstones of chemistry, I thought I’d attempt to produce a more dynamic looking version. The result is the above table – each element is shown within a circle that contains a variety of data pertaining to that element. The data shown for each element is as follows: Melting point in degrees celsius.Boiling point in degrees celsius.First ionisation energy in kilojoules per mole.Atomic radius in angstroms.Electronegativity (on the Pauling scale).Density (in grams per centimetre cubed (g/L for gases)).

What is chemical energy? Chemical energy Chemical Energy is energy stored in the bonds of chemical compounds (atoms and molecules).

What is chemical energy?

It is released in a chemical reaction, often producing heat as a by product (exothermic reaction). Batteries, biomass, petroleum, natural gas, and coal are examples of stored chemical energy. Usually, once chemical energy is released from a substance, that substance is transformed into an entirely new substance. For example, when an explosive goes off, chemical energy stored in it is transferred to the surroundings as thermal energy, sound energy and kinetic energy. Kinetic and Potential Energy. Kinetic energy is energy possessed by a body by virtue of its movement.

Kinetic and Potential Energy

Potential energy is the energy possessed by a body by virtue of its position or state. While kinetic energy of an object is relative to the state of other objects in its environment, potential energy is completely independent of its environment. Hence the acceleration of an object is not evident in the movement of one object, where other objects in the same environment are also in motion. For example, a bullet whizzing past a person who is standing possesses kinetic energy, but the bullet has no kinetic energy with respect to a train moving alongside.

Text below taken from Kinetic Theory of Gases: Molecular Speeds Other sections state that increasing the temperature increases the speeds at which molecules move.

We are now in a position to find just how large that increase is for a gaseous substance. Combining the ideal gas law with Eq. (1) from The Total Molecular Kinetic Energy, we obtain. Distillation.

Simulations of the Universe on the largest scales show an unexpected resemblance to nerve cells in the human brain, with galaxy clusters playing the role of the cell body and thinner filaments of matter linking them like axons.

Galaxy surveys (such as the Sloan Digital Sky Survey, or SDSS) show that galaxies do cluster like our simulations predict. But the filaments that should connect them have been harder to find. Most of the mass in the Universe is dark matter—material that neither emits nor absorbs light—and filaments are predicted to be mostly dark matter: no galaxies, little hot gas. Einstein's general theory of relativity, however, tells us mass affects the path of light, and a group of astronomers have identified a dark matter filament by measuring this effect.

We encounter thousands of chemical reactions every day: plants use them in photosynthesis, metals rust over time, and combustion reactions provide us with heat and light, among thousands of other daily uses. Chemical reactions occur when reactants transform into new substances, called products, through creating and breaking bonds between atoms. Sometimes the process creates some pretty wild effects.
