The lowest temperature theoretically attainable (at which the kinetic energy of atoms and molecules is minimal); 0 Kelvin or -273.15 Celsius or -459.67 Fahrenheit.
The units of measurement for energy derived from the Latin "calor" (heat). One calorie is equal to the energy needed to increase the temperature of 1 gram of water by 1 degree Celsius.
A system that can neither gain nor lose energy. Also known as an isolated system.
The transfer of heat via collisions between atoms and molecules in the substance and the subsequent transfer of kinetic energy. The transfer of heat is normally from a high temperature object to a lower temperature object.
Conservation of Energy
The fundamental principle of physics that the total energy of an isolated system is constant despite internal changes.
The transfer of heat through fluid (liquid or gas) caused by molecular motion. The transfer of heat is normally from a high temperature substance to a lower temperature substance.
When a volume of fluid is heated, it expands and becomes less dense, and thus more buoyant than the surrounding fluid. The colder, more dense fluid settles underneath the warmer, less dense fluid and forces it to rise. Such movement is called convection, and the moving body of liquid is referred to as a convection cell.
Density is the mass per unit of volume, or D=m/V. This property of matter helps distinguish one material from another. Since mass is usually expressed in grams (g) and volume in cubic centimeters, density is expressed in gram/cubic centimeters.
Elastic Potential Energy
Potential energy that is stored when a body is deformed (as in a coiled spring or stretched rubber band).
Waves that travel at the speed of light; electromagnetic waves include radio waves, X-rays, and gamma rays, as well as infrared, ultraviolet, and visible light.
A measure of the amount of disorder in an isolated system.
The force of resistance encountered when one body is moved in contact with another.
A symbol for the average acceleration produced by gravity at the Earth's surface.
Gravitational Potential Energy
The kind of potential energy that results when something is separated from the Earth.
A measure of the amount of energy transferred between objects of different temperatures.
Electromagnetic radiation with wave lengths longer than visible light but shorter than radio waves.
The energy associated with the random, disordered motion of molecules.
A unit of energy, which is defined as the potential to do work.
The energy an object possesses when it is in motion.
When graphed, the relationship between two variables forms a straight line.
The physical property of an object that quantifies the amount of matter it contains.
The energy that an object has due to its position or shape.
A method of energy transfer from one object to another than does not require the object to be in direct contact. Radiation can occur via rays or waves.
Second Law of Thermodynamics
A physical law that states that the entropy of an isolated system tends to increase, indicating that there is less available energy to perform mechanical work.
A measure of the heat energy possessed by an object or substance.
Thermal energy is a measure of both the kinetic and potential energy contained in the molecules of an object.
A compromise between various aspects of an exchange.
