Acid
Any substance that produces hydrogen ions, H+, in a water solution.
Base
any substance that forms hydroxide ions, OH-, in a water solution.
Chemical Property
any characteristic of a substance, such as flammability, that indicates whether it can undergo a certain chemical change.
Conduction
Transfer of energy through matter by colliding particles.
Convection
Transfer of energy by the motion of heated particles in a fluid.
Density
the amount of mass per unit volume of a material.
Electrolyte
compound that breaks apart in water forming charged particles (ions) that can conduct electricity.
Kinetic Theory of Matter
explanation of behavior of molecules of matter; states that all matter is made of constantly moving particles that collide without losing energy.
pH scale
a measure of the concentration of hydronium ions in a solution using a scale ranging from 0 to 14 with 0 being the most acidic and 14 begin the most basic.
Physical Property
any characteristic of a material, such as size or shape, that you can observe or attempt to observe without changing the identity of the substance.
Radiation
Transfer of energy in the form of electromagnetic waves.
Saturated solution
any solution that contains all the solute that it can hold at a given temperature.
Solubility
maximum amount of solute that can be dissolved in a given amount of solvent at a given temperature.
Specific Heat
Amount of energy needed to raise the temperature of 1 kg of a material 1 K (1 °C).
Sublimation
temperature and pressure at which a solid becomes a gas
Temperature
a measure of the average kinetic energy of all the particles in an object.
