What is the NFPA diamond?
This is the ratio of the amount of material that returns to the distillation column to the amount of material that is collected in the distillate.
What is the Reflux Ratio?
This process separates the components from a liquid mixture by selective evaporation and condensation.
What is Distillation?
This law states that the electric potential difference between two points is proportional to current flow.
What is Ohm’s Law?
The rock cycle describes the transitions between magma and this many different types of rocks.
What is 3?
“Eat Fresh.”
What is Subway?
The 3 sides of the fire triangle.
What are oxidizer, fuel and ignition source?
The McCabe-Thiele Method and Diagram are used to determine the theoretical number of these.

What are Plates, Trays or Stages?
The Haber-Bosch process is used to convert atmospheric nitrogen and hydrogen to this hazardous gas.
What is Ammonia?
This circuit element resists changes in electric current.
What is an Inductor (coil, reactor)?
Radiocarbon dating determines the age of organic material by using the properties of this carbon isotope.
What is 14C?
“Snap! Crackle! Pop!”
What is Rice Krispies?
This type of flow is generally assumed when sizing a relief valve for a runaway reaction.
What is 2-phase flow?
This is a mixture which when vaporized produces the same composition as the liquid and cannot be distilled past that composition.
What is an Azeotrope?
This process transfers solute from a feed solution to an immiscible solvent and is common in nuclear reprocessing and the production of fine organic compounds.
What is Liquid-liquid Extraction or Solvent Extraction or Partitioning?
Invented by Benjamin Franklin, this protects buildings from the discharge of atmospheric charge.
What is a Lightning Rod?
This type of rock is generally formed through the cooling and solidification of magma or lava.
What is Igneous Rock?
“Taste the Rainbow.”
What is Skittles?
This is the power to which the volume (V) is raised in the following equation when experimental explosion data are used to determine the explosive behavior of materials in process vessels.

What is 1/3?
In this type of distillation, the column pressure is reduced causing evaporation of the most volatile component.
What is a Vacuum Distillation?
This process is designed to remove gas pollutants using a liquid solvent.
What is Scrubbing or Absorption?
This type of material produces electricity when a mechanical stress is applied.
What is Piezoelectric?
This type of boundary commonly has tectonic plates that move toward one another and collide, forming mountain ranges.
What is Convergent Boundary?
“Because You’re Worth It.”
What is L’Oreal?
This type of electrostatic discharge can occur in the situation shown below.

What is a propagating brush discharge or a Lichtenberg discharge?
These allow for easier and more controlled boiling due to the porous surface and cavitation sites.
What are Boiling Stones/Chips?
This process uses heat and a reducing agent to purify ore, removing gas or slag and leaving just the metal base behind.
What is Smelting?
The equivalent resistance of four 100Ω resistors in parallel.
What is 25Ω?
This peak, which is almost over 9,000 m tall, is still growing at nearly 2 cm/year.
What is Mt. Everest?
“Don’t Be Evil.”
What is Google?
