thermal energy transfer Flashcards
(13 cards)
what is matter
anything that takes up and has mass
what are the states of matter
one of the form that matter can take including solid liquid and gas
energy
kinetic energy
the energy of an object because of motions
thermal energy
it important to remember that an object or system does not have heat heat is the transfer due to temperature
temporature
the averages kinetic energy of the particles of an object or substance
heat
the flow of enegry form warmer place to cooler places to difference in temperature
conduction
IS THE TRANSFER OF HEAT THOUGH A SOLID MATTER BY DIRECT CONTACT OF PARTICLES
convection
the transfer of heat in a fluid(air or liquid)
where hotter less dense fluids rise and cooler more dense fluids sink
radation
the transfer of heat through empty space by invisible eletrom
thermal equilbrium
a state in which two objects in
conductor
matter that allow heat energy to move through theme efficient are called conductors
insulator
