physical properties of materials Flashcards
define solubility:
the ability of a solute to dissolve in a solvent.
what is a solute?
the substance that gets dissolved.
what is a solvent?
the substance that does the dissolving.
define heat (thermal energy):
the flow of energy when there is a temperature difference within one or between two materials.
define thermal conductivity:
how well a material can conduct (transfer) heat energy.
how does conductive heat transfer occur?
when energy is transferred through the collisions (vibrations) between the particles in a material.
define electrical conductivity:
how well a material can conduct (transfer) an electrical charge.
define melting point:
the temperature at which a material changes states from a solid to a liquid.
how does melting point occur?
when sufficient heat is transferred to a solid, the particles separate becoming a liquid.
what makes a material a solid?
solid materials are composed of particles packed closely together.
define boiling point:
the temperature at which a material changes states from a liquid to a gas.
how does boiling point occur?
when sufficient heat is transferred to a liquid, the particles separate becoming a gas.
