How an Aerosol Can Works
At one time or another, most of us have probably used an aerosol can. With just a push of the button, we easily and quickly apply just the right amount of furniture polish, bathtub cleanser, or underarm deodorant. It is obvious to us that the aerosol can is more convenient than the old-fashioned jars of liquid polish or cans of powdered cleanser, which can spill or be applied too thickly. At the same time, however, most of us probably do not know how the aerosol can works. We accept its ease and convenience without realizing that the aerosol can is quite a complex container.
An aerosol is not a simple cleaner or polish; it is a colloidal system. That means it consists of finely divided liquid or solid particles, called a product, dispersed in and surrounded by a gas. The most commonly used gases, or propellants, are chlorinated hydrocarbons, butane, propane, isobutane, vinyl chloride, and nitrogen. Nitrogen is used particularly for products when the taste or smell of the propellant is not desired in the product, for ex...

6 Week Training Program For my GSCE Coursework I decided to perform a circuit-training programme for the sport of tennis. This durated for six weeks. I am already an experienced tennis player so this is to be taken into consideration with training procedures and results.
Investigating How the Concentration of Hydrochloric Acid Affects the Rate of Reaction with Calcium Carbonate
Process philosophy is known as the idea that everything is changing. Over the years, process philosophy has changed the way humans exist and go about their day to day lives. In order to fully grasp the concept of process philosophy we will first take a closer look at process philosophy, as a whole, its history, and the ideas behind this particular philosophy. Then we will discuss the effects process philosophy has had on marriage and family, followed by a brief commentary.
Investigating the Effect of Enzyme Concentration on the Hydrolysis of Starch with Amylase Aim: Investigate the effect of enzyme concentration on the rate of an enzyme-controlled reaction. Using amylase and starch as my example. Introduction: I am investigating the effect of the concentration of the enzyme, amylase on the time taken for the enzyme to fully breakdown the substrate, starch to a sugar solution. The varied variable will be the concentration and all other variables are going to be fixed. The different concentrations will be: 0.5% 0.75% 1.0% 1.5% 2% An enzyme is a class of protein, which acts as a biological catalyst to speed up the rate of reaction with its substrates.
Nitrogen gas makes up about 78% of the air, and most of this gas just passes right through the car. Carbon dioxide is one of the products of combusion. The carbon in the fuel bonds with the oxygen in the air to form carbon dioxide. Water vapor is the other product of combusion. The hydrogen in the fuel bonds with the oxygen in the air to form water vapor. However, the combustion process is never perfect, so some smaller amounts of more harmful emissions are also produced in car engines. They include carbon monoxide, hydrocarbons or volatile organic compounds, and nitrogen oxides. These are the three main regulated emissions, and also the ones that catalytic converters are designed to reduce.

Aerogel was discovered in the late 1930’s by chemist Samuel Stephens Kistler. He accomplished this by the process of supercritical fluid drying. A supercritical fluid is any substance at a temperature and pressure above its critical poi...

Contamination of Water and Air. Urbanization enhances the proliferation of industries, automobiles, and agricultural practices. Most toxic air contaminants are produced as we endeavor to fuel our homes, automobiles, factories, energy production facilities, and might also be discovered in indoor cleansing mixtures, and construction supplies. Furthermore pollutants found in gasoline, dry cleaning services, and paint thinners and strippers; som...

Process Management can be defined as a concept which helps integrate performance excellence and quality into the strategic management of organizations. Process management includes activities such as defining a process, establishing responsibilities, evaluating process performance and also identifying opportunities for improvement. Innovation, on the other hand, can be defined as the conversion of knowledge and ideas into new or improved products, processes or services to gain competitive advantage. After reading the first article it is clear that it focuses mainly on three different programs that are associated with process management. These three processes are listed as TQM, ISO 9000, and Six Sigma.
Magic tricks have fascinated people of all ages for centuries. From David Copperfield to Chris Angel, many performers use magic to amaze and astound. One of the least elaborate types of magic tricks is the card trick. There are two main types of card tricks: there are mathematical card tricks and sleight of hand card tricks. The former are simple to learn, but do not impress audiences. To really attract attention, an aspiring magician should learn sleight of hand card tricks. Sleight of hand card tricks are tricks that use misdirection and special manipulations of a deck of cards to do something seemingly impossible. The techniques involved require much practice. While performing a sleight of hand trick, a magician must constantly be distracting the audience. Because of this, many people believe that they are not capable of learning sleight of hand magic. In order to prove them wrong, I will describe a simple sleight of hand trick that anyone can learn, as long as they remember that we all have the potential inside of us to do magic.
Factories and transportation depend on huge amounts of fuel--billions of tons of coal and oil are consumed around the world every year. When these fuels burn they introduce smoke and other, less visible, by-products into the atmosphere.
