Thermal Energy Flashcards
the measure of the average kinetic energy of the particles in matter
temperature
the total kinetic energy of moving particles of matter
thermal energy
factors of thermal energy
mass and temperature
transfer of thermal energy
heat
thermal energy always transfers from ____________________ substances
warmer to cooler
thermal energy is transferred until both substances have the same _______________
temperature
ice cools down a warm soda by accepting ___________________ from the soda
thermal energy
example of a substance without thermal energy
none - all substances have thermal energy
SI unit for temperature
degrees Kelvin
SI unit for thermal energy
Joule
If two objects have the same temperature, but different masses, which one will have more thermal energy?
the one with greater mass
If two objects have the same amount of thermal energy, but different masses, which one will have the higher temperature?
the one with lower mass
If two objects have the same temperature, which one will have less thermal energy?
the one with lower mass
If two objects have the same thermal energy, which one will have the lower temperature?
the one with greater mass
the transfer of thermal energy between particles of matter that are touching
conduction
thermal energy is always transferred from matter with a ______________ energy to matter with a ____________ energy
higher, lower
particles of warmer matter move more__________ than particles of cooler matter
quickly
particles of cooler matter move more __________ than particles of warmer matter
slowly
this phase of matter conducts thermal energy better than other phases
solid
this type of material conducts thermal energy better than other types
metal
metals conduct thermal energy really well because they have
free unlocalized electrons
form of heat transfer that occurs in solids
conduction
form of heat transfer in which substances maintain their density
conduction
form of heat transfer in which molecules stay in place
conduction
