Science Ch 6 Voc Flashcards
Measure of the average kinetic energy of all the particles in an object
Temperature
Sum of the kinetic and potential energy of the particles in an object
Thermal energy
Thermal energy that flows from a warmer material to a cooler material
Heat
Amount of thermal energy needed to raise temperature of 1 kg of a material 1 degree C
Specific heat
Transfer of thermal energy by collisions between particles in matter at a higher temperature and particles in matter at a lower temperature
Conduction
Transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from one place to another
Convection
Transfer of thermal energy by electromagnet waves
Radiation
Material in which electrons are not able to move easily
Insular
Device used in an active solar heating system that absorbs radiant energy from the sun
Solar collector
Study of the relationship between thermal energy, heat and work
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
1st Law of Themodynamics
Heat engine that burns fuel inside the engine in chambers or cylinders
Internal combustion engine
Device that converts thermal energy into work
Heat engine
States that it is impossible for heat to flow from a cool object to a warmer object unless work is done
2nd Law of Thermodynamics
