27.6 F
Fahrenheit scale
The most commonly used scale in the United States, defines the normal freezing point and boiling point of
water as 32°F and 212°F, respectively.fatty acid
Are cleaved from triglycerides in the small intestine.filtration
A method used to separate substances in mixtures where at least one component has particles that are large
enough in size to be captured by a porous material.first law of thermodynamics
Energy can be converted from one form to another, but cannot be created or destroyed.first-order reaction
The rate is dependent upon the reactant concentration raised to the first power.fission
Nuclear fission reactions involve collision of a slow neuron with an element, usually uranium. The products
of a fission reaction are two smaller isotopes, more neutrons, and heat energy.force
Ability to do work.formula mass
The sum of masses of all the atoms represented in a chemical formula.free element
Uncombined state where each atom has an oxidation number of zero.freezing point depression
The addition of solute to a pure solvent will decrease the freezing point of the solution by a measurable
amount.frequency
Inversely proportional to wavelength. Photons with high frequency light have more energy than photons with
low frequency light (Zukav 1979).frost
A solid form of water.fuel cell
Employ oxidation-reduction reactions of hydrogen and oxygen gases ad a platinum catalyst.
