Melting Point (also freezing point). Point at which the crystals of a pure substance are in equilibrium with the liquid phase at atmospheric pressure. Melting point is when substance is approaching it from its solid state, and freezing point when approaching it from its liquid state.
Heat capacity: Quantity of heat required to produce a unit temperature rise per mole of material.
Emissivity: Ratio of radiation emitted by a body to the radiation that would be produced by a perfect black body radiator of the same temperature in the same environment.
Heat capacity: Ratio of amount of heat transfer applied to a body to the change in temperature produced by this heat. Usually expressed as heat energy required to raise temperature on a specific substance by 1 degree Centigrade at constant pressure and volume.
Oxication potential: Difference in the amount of energy contained in an atom or an ion and the amount of energy remaining once an electron leaves its orbit.
Magnetic Moment: a property associated with a magnetic domain or magnetized body, equal to the maximum torque experienced by the body divided by the magnetic induction acting on the body, generally measured in units of magnetons.
Joule The SI unit of energy, equal to the work required to move a 1 kg mass against an opposing force of 1 newton. 1 J = 1 kg m2 s-2 = 4.184 calories.
kelvin or Kelvin Thermodynamics. 1. the fundamental SI unit of temperature, equal to 1/273.16 of the absolute temperature of the triple point of pure water. A temperature increment of one degree kelvin .
dynamic equilibrium. equilibrium. Compare with position of equilibrium.
Dynamic equilibrium is established when two opposing processes are occuring at precisely the same rate, so that there is no apparent change in the system over long periods of time.
Watt. A common unit used in measuring power. Power is defined as the flow of energy over time.
