### substance:

Dielectric material
* are the strongest collectors of electromagnetic energy known.
* enhance the charge storage of a capacitor.

### substance:

Different material
* Many different materials can exist in the voids in rocks and unconsolidated sediments
  - used by humans come from the earth
* Most different materials have conductivity
  - density
* Most different materials have different density
  - mass density
  - heat capacity
  - properties
* absorb different wavelengths of light.
* are distinguished from each other by their different optical densities
  - easier to absorb the energy of waves which frequency is in specific range
* can hold different amounts of heat.
* come into contact.
* condense at different temperatures.
* conduct heat at different rates
  - thermal energy at different rates
* consume different amounts of energy.
* convert different amounts of energy.
* emit different spectra as they burn.
* expand at different rates when they're heated.
* expand by different amounts for a given change in temperature
  - when their temperature is raised by one degree
* have capacity
* have different affinities to a selected liquid and the air bubbles introduced
  - coefficients of thermal conductivity
  - electrical conductivities
  - energy levels
  - engineering properties
  - insulating ability, or dielectric strength s
  - rates at which organized motion is turned into heat
  - reflection parameters
  - relationships between internal energy and temperature
  - underlying lattices and different kinds of basis
  - vastly different properties
* liquify or boil off at different temperatures.
* offer resistance.
* produce different amounts of friction.
* radiate at different levels of efficiency.
* react differently to variations in temperature and pressure.
* reflect and absorb differently at different wavelengths.
* refract light differently.
* require different amounts of heat.
* respond to applied stresses in different ways
  - different wavelengths and are thus spectrally selective
* shrink and expand at different rates.
* transfer heat in different ways depending on their physical properties.

### substance:

Different substance
* Many different substances can affect the health of children
  - cause an allergenic reaction
  - create PD symptoms by depleting dopamine in the brain
  - cause allergic reactions
  - go into making fireworks
* Most different substances have density
* Some different substances have capacity
  - vapor pressure
* absorb heat at different rates.
* can damage the body and how it functions.
* exhibit different densities.
* form different types of crystals.
* have different aura both in length and breadth, and also in luminosity
  - heat capacities
  - melting points, boiling points and densities
* produce different crystals.
* react differently to the ray.
* require different amount of heat for the same rise in temperature.
* vary greatly in the speed at which they evaporate at a given temperature.
+ Crystal: Chemistry
  * Different substances form different types of crystals. The study of the various kinds is crystallography.
+ Temperature, Heat capacity: Weather measurements :: Heat :: Physical quantity :: Thermodynamics :: Basic physics ideas
  * The amount of heat that is needed to make a substance one degree higher is called its heat capacity. Different substances have different heat capacities. For example, a kilogram of water has more heat capacity than a kilogram of steel.

Diorite
* contain sodium plagioclase.
* is an igneous rock

Dissolved substance
* form crystals as the solvent evaporates.
* lower the free energy of water.
