9th Grade Physical Science Ch. 6: Thermal Energy

question

temperature
answer

the measure of the average kinetic energy of the particles in the object.
question

thermal energy
answer

the sum of the kinetic and potential energy of all the particles in an object.
question

heat
answer

thermal energy that flows from something at a higher temperature to something at a lower temperature.
question

specific heat
answer

amount of thermal energy needed to raise the temperature of 1 kg of a material 1degree C
question

conduction
answer

the transfer of thermal energy by collisons between particles in matter
question

radiation
answer

the transfer of energy by electromagnetic waves.
question

insulator
answer

a material in which heat flows slowly
question

convection
answer

the transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from place to place.
question

solar collectors
answer

absorb radiant energy from the sun
question

thermodynamics
answer

the study of relationships between thermal energy, heat, and work
question

first law of thermodynamics
answer

the increase in thermal energy of a system equals the work done on the system plus the heat transferred to the system.
question

second law of thermodynamics
answer

states that is is impossible for heat to flow from a cool object to a warmer object unless work is done.
question

heat engine
answer

a device that converts heat into work
question

internal combustion engine
answer

heat engine that burns fuel inside the engine in chambers or cylinders.
