Glossary
Combined Gas Law
Explains the relationship between pressure, volume, and temperature in a fixed amount of gas.
Boyle’s Law
States that gas pressure decreases as its volume increases, keeping temperature constant.
Charles’s Law
Shows that gas expands when heated, provided the pressure remains constant.
Ideal Gas Law
Combines several gas laws into one formula involving pressure, volume, temperature, and moles.
Gibbs Free Energy
Predicts whether a reaction will occur spontaneously based on energy changes.
pH
Measures how acidic or basic a solution is on a scale from 0 to 14.
pOH
The counterpart of pH, focusing on hydroxide ion concentration in solutions.
pKa
Indicates the strength of an acid; the smaller the value, the stronger the acid.
Molarity
The concentration of a solution, defined as moles of solute per liter of solution.
Stoichiometry
Involves using balanced equations to calculate the amounts of reactants or products.
Limiting Reactant
Determines the maximum amount of product that can be formed in a reaction.
Percent Yield
Compares the actual product obtained to the theoretical maximum possible.
Dilution
The process of reducing solution concentration by adding more solvent.
Rydberg Equation
Helps calculate the wavelengths of light emitted or absorbed by electrons in atoms.
Thermodynamic Equilibrium Constant
Provides insight into the ratio of product to reactant concentrations at equilibrium.
Energy Conversion
Allows for the translation of energy measurements across units like joules, calories, and kilowatt-hours.
Pressure
A measure of force exerted by gas particles per unit area.
Volume
The three-dimensional space occupied by gas, liquid, or solid substances.
Temperature
Reflects the average kinetic energy of particles in a substance, often measured in Kelvin.
Chemical Equilibrium
Occurs when the forward and reverse reactions proceed at the same rate.
Fun Facts About the Calculators
Here’s a list of fun chemistry facts that relate to the calculators you mentioned:
- Gases can be “shrunk”! Boyle’s Law explains why scuba tanks can store so much air in a tiny space.
- Hot air balloons rise thanks to Charles’s Law, which shows that gases expand when heated.
- The Ideal Gas Law is universal, used to predict how gases behave from the depths of the ocean to outer space.
- Acids aren’t always scary! Citrus fruits owe their tangy flavor to acids like citric acid with measurable pH.
- The pH scale was invented in 1909 by Danish chemist Søren Sørensen—he probably didn’t imagine it would be used worldwide for food, science, and health.
- Your stomach acid is super strong! It has a pH of 1-2, which is powerful enough to dissolve metal.
- Water can act as both acid and base, which is why it plays a crucial role in neutralization reactions.
- Hydrogen ions (H⁺) are tiny but mighty, responsible for the acidity of all solutions.
- Ever wondered why soda fizzes? The carbon dioxide inside is under high pressure, tied to the gas laws.
- Dry ice “smokes” without melting, because carbon dioxide sublimates directly from solid to gas.
- Chemical reactions are picky! The limiting reactant determines exactly how much product you get.
- The Rydberg Equation helped decode the colors of stars, linking atomic structure to the universe.
- Energy changes make reactions exciting! Exothermic reactions release heat, while endothermic ones absorb it.
- Dilution is like chemistry math, where you can create just the right concentration for lab experiments.
- Liquid nitrogen boils at room temperature! Its extremely low boiling point (-196°C) relates to pressure laws.
- Ammonia production using the Haber process relies heavily on the Ideal Gas Law to control conditions.
- Gibbs Free Energy reveals the secret of life! It explains why biological processes like photosynthesis work.
- Your blood pH stays constant thanks to buffers, which use pKa to keep your body balanced.
- Molarity helps make medicines precise, ensuring the exact concentration for treating patients.
- Chemistry in fireworks is stoichiometry at work! The colors and blasts are perfect reactant ratios.
