What is Applied Chemistry?
© 2011 Project Lead The Way, Inc.Science of Technology
What is Chemistry?
The branch of science concerned with the properties of substances and the interactions between different types of matter.
Using detergents to clean clothes
Cooking and baking
Determining which medication is appropriate and the dosage
What is Chemical Engineering?
• Applied chemistry• Engineering concerned with design,
construction and operation of machines that perform chemical reactions, separations/mixing and fluid flow to solve problems and make useful products.
What’s an Atom?
The smallest unit of a chemical element that contains all properties of that element
Components of an AtomNucleusThe center portion of an atom containing the protons and neutrons
ProtonsPositively charged atomic particles
NeutronsUncharged atomic particles
ElectronsNegatively charged atomic particles that orbit the nucleus
What is an Element?A pure substance, composed of only one
type of atom.Periodic Table of Elements
What is a Molecule?• 2 or more atoms bonded
together, sharing electrons
• Small particles that make up all living and non-living things
• Each molecule has a unique arrangement that allows it to interact with other molecules
What is the difference between a chemist and chemical engineer?
ChemistA chemist studies chemicals, matter and its properties, and atoms in order to understand how elements join together to form different substances.
Chemical EngineerWorks in collaboration with chemists to develop chemicals for useful purposes.
What does a chemist do?
• Chemists study atoms and how they join together
• Chemists use their knowledge of how atoms combine to discover new products
• Chemists work to develop new drugs to treat diseases
• Chemists also work in the oil industry to find better ways to refine oil to make fuel burn cleaner
Chemical Engineers… are
concerned with air quality, pollution and atmosphere conditions.
Chemical Engineers…Help solve problems related to world hunger
Chemical Engineers…
Develop new sources of environmentally clean energy.
Chemical Engineers…Produce pharmaceuticals as well as life-saving devices such as the artificial kidney.
Chemical Engineers…Develop processes and chemicals to make food less expensive, safer and with higher yields.
Chemical Engineers…
Design industrial facilities that provide materials, petroleum products and plastics.

Chemical Engineers study…
• Chemistry• Mathematics• Physics• Biology• Geology• Economics• Political science• Psychology• Computer science
Industries for which a Chemical Engineer may work:
• Pharmaceuticals– Large scale manufacturing of drugs– Economical and safe manufacturing
• Materials– Shampoo that leaves your hair shinier– Athletic clothing that absorbs sweat
• Alternative energy– Solar power– Bio-fuels
• Manufacturing– Food– Plastics
• Health Care– Lotions– Make-up
