science Flashcards
the energy an object has due to its motion.
kinetic energy
a measure of the average kinetic energy of the particles of a substance.
temperature
describe two quantities that are related by a ratio
proportional
energy transferred from a hotter object to a cooler object.
heat
the transfer of energy from one part of a material to another or between two objects that are in physical contact with each other
conduction
the transfer of energy by light
radiation
the transfer of energy caused by the circulation of matter due to differences of density
convection
the change of state of particle from a gas to liquid
condensation
the changes of state of particle from a liquid to a gas at the surface of the liquid.
evaporation.
