-
a measure of the average kinetic energy of all the particles in an object
temperature
-
total energy, including kinetic and potential energy, of the particles that make up a material, is transferred by conduction, convection, and radiation
thermal energy
-
thermal energy that flows from a warmer material to a cooler material and is measured in joules
heat
-
amount of energy needed to raise the temperature of 1kg of a material by 1k
specific heat
-
transfer of energy through matter by colliding particles, takes place because particles are in constant motion
conduction
-
transfer of energy by the motion of heated particles in a fluid
convection
-
transfer of energy in the form of electromagnetic waves
radiation
-
material that doesn't allow electrons to move through it easily
insulator
-
energy from the sun that is free, renewable, and can be used to heat homes and buildings
solar energy
-
solar heating system device that absorbs radiant energy from the sun
solar collector
-
device that converts thermal energy produced by combustion into mechanical energy
heat engine
-
a type of heat engine that burns fuel inside the engine
internal combustion engine
-
device, such as a refrigerator, that removes thermal energy from one place and transfers it to another place at a different temperature
heat mover
-
specific heat
the amount of heat needed to raise the temperautre of 1kg of a substance by 1k
-
thermal energy of an object
the total kinetic and potential energy of the molecules in the object
-
what is thermal energy transferred by?
conduction, convection, and radiation
-
when does conduction and convection occur?
conduction and convection can only occur matter is present
