In chemistry and physics, activation energy is the energy which must be available to a chemical or nuclear system with potential reactants to result in: a chemical reaction, nuclear reaction, or other various other physical phenomena.
In thermodynamics, an adiabatic process is one that occurs without transfer of heat or matter between a thermodynamic system and its surroundings.
Aluminium or aluminum is a chemical element with symbol Al and atomic number 13.
Atmospheric pressure, sometimes also called barometric pressure, is the pressure within the atmosphere of Earth (or that of another planet).
The bar is a metric unit of pressure, but is not approved as part of the International System of Units (SI).
Benzoic acid, C7H6O2 (or C6H5COOH), is a colorless crystalline solid and a simple aromatic carboxylic acid.
Biochemistry, sometimes called biological chemistry, is the study of chemical processes within and relating to living organisms.
A calorie is a unit of energy.
In particle physics, a calorimeter is an experimental apparatus that measures the energy of particles.
A calorimeter constant (denoted Ccal) is a constant that quantifies the heat capacity of a calorimeter.
Calorimetry is the science or act of measuring changes in state variables of a body for the purpose of deriving the heat transfer associated with changes of its state due, for example, to chemical reactions, physical changes, or phase transitions under specified constraints.
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.
Chemical stability when used in the technical sense in chemistry, means thermodynamic stability of a chemical system.
In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object.
Enthalpy is a property of a thermodynamic system.
Enzymes are macromolecular biological catalysts.
In thermodynamics, the term exothermic process (exo-: "outside") describes a process or reaction that releases energy from the system to its surroundings, usually in the form of heat, but also in a form of light (e.g. a spark, flame, or flash), electricity (e.g. a battery), or sound (e.g. explosion heard when burning hydrogen).
Gold is a chemical element with symbol Au (from aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally.
In thermodynamics, heat is energy transferred from one system to another as a result of thermal interactions.
Heat capacity or thermal capacity is a measurable physical quantity equal to the ratio of the heat added to (or removed from) an object to the resulting temperature change.
Heat flux or thermal flux, sometimes also referred to as heat flux density or heat flow rate intensity is a flow of energy per unit of area per unit of time.
The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it.
Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy (heat) between physical systems.
In mathematics, an integral assigns numbers to functions in a way that can describe displacement, area, volume, and other concepts that arise by combining infinitesimal data.
Joule heating, also known as Ohmic heating and resistive heating, is the process by which the passage of an electric current through a conductor produces heat.
The mole, symbol mol, is the SI unit of amount of substance.
The National Renewable Energy Laboratory (NREL), located in Golden, Colorado, specializes in renewable energy and energy efficiency research and development.
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
Physical changes are changes affecting the form of a chemical substance, but not its chemical composition.
A polymer (Greek poly-, "many" + -mer, "part") is a large molecule, or macromolecule, composed of many repeated subunits.
Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
A reaction calorimeter is a calorimeter that measures the amount of energy released (exothermic) or absorbed (endothermic) by a chemical reaction.
Colloquially, room temperature is the range of air temperatures that most people prefer for indoor settings, which feel comfortable when wearing typical indoor clothing.
In chemistry, a solution is a special type of homogeneous mixture composed of two or more substances.
Stoichiometry is the calculation of reactants and products in chemical reactions.
Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam (XPS), commonly called "Blue Board" manufactured as foam continuous building insulation board used in walls, roofs, and foundations as thermal insulation and water barrier.
Temperature is a physical quantity expressing hot and cold.
Thermal conduction is the transfer of heat (internal energy) by microscopic collisions of particles and movement of electrons within a body.
Thermal insulation is the reduction of heat transfer (i.e. the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence.
In building design, thermal mass is a property of the mass of a building which enables it to store heat, providing "inertia" against temperature fluctuations.
A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming electrical junctions at differing temperatures.
Titration, also known as titrimetry, is a common laboratory method of quantitative chemical analysis that is used to determine the concentration of an identified analyte.
