PS CH6 vocab.

TermDefinition
temperature measure of the average kinetic energy of all the particles in an object
thermal energy sum of the kinetic and potential energy of the particles in an object is transferred by conduction convection and radiation
heat thermal energy that flows from a warmer material to a cooler material
specific heat amount of thermal energy needed to raise the temperature of 1 kg of a material
conduction transfer of thermal energy by collisions between particles in matter at a higher temperature and particles in matter at a lower temperature
convection transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from one place to another
radiation transfer of thermal energy by electromagnetic waves
insulator material in which electrons are not able to move easily
solar colector device used in an active solar heating system that absorbs radiant energy from the sun
thermodynamics study of the relationship between thermal energy heat and work
first law of thermodynamics states that the increase in thermal energy of a system equals the work done on the system plus the heat added to the system
second law of thermodynamics states that is impossible for heat to glow from a cool object to a warmer object unless work is done
heat engine device that converts thermal energy into work
internal combustion engine heat engine that burns fuel inside the engine in chambers or cylinders
