IPC Test 1/26/15 Flashcards
What is a calorimeter
A device used to measure heat energy
Dark clothes are better
conductors
More dense things are better
conductors
Heat you feel when you put your hands above a fire
convection
the total energy of the particles in a material
thermal energy
thermal energy includes
potential energy and kinetic energy
the measure of average kinetic energy
temperature
energy that flows from something with a higher temp to something with a lower temp
heat energy
the heat lost by one object is equal to the heat gained by the other object
1st law of thermodynamics
as the temp of a material increases the particles move faster and their average __________ becomes greater
kinetic energy
the transfer of energy through the movement of matter
convection
transfer of energy through direct contact
conduction
transfer of energy through a vacuum
radiation
what kind of energy transfers in waves
radiation
type of heat transfer that doesn’t require matter
radiation
convection takes place in
fluids
fluids are
liquids and gases
a material that doesn’t allow heat to pass through it
insulator
many conductors are
metals
insulators are poor conductors of
heat
the transfer of heat through conduction and convection require
matter
what kind of heat transfer is it when you put your hands above a fire
convection
cooking food in a microwave uses
radiation
insulation is used to prevent this type of heat transfer
convection
heated fluids and particles rising
convection
infared heat waves like on the electromagnetic spectrum
radiation
heat that causes a kettle to whistle
convection
heat you feel sitting next to a campfire
radition
