Conductor
a material that easily transfers heat between its particles
Insulator
a material that does not easily transfer heat between its particles
Conduction
the direct transfer of heat from one substance to another substance that it is touching
Convection
the transfer of thermal energy by the movement of a fluid
Radiation
energy that is radiated or transmitted in the form of rays or waves or particles
Covection Current
a circulation pattern in which material is heated and rises in one area, then cools and sinks in another
Thermal Energy
The total potential and kinetic energy of the particles in an object
Kinetic Energy
the energy an object has due to its motion
Heat Transfer
the movement of energy from a warmer object to a cooler object
Temperature
A measure of how hot or cold something is
Specific Heat
the amount of energy needed to raise one gram of a substance by one degree Celsius
Joule
metric unit of work and energy
Thermal Equilibrium
two objects are at the same temperature; there is no flow of heat between them
Absolute Zero
the zero point on the Kelvin temperature scale, equivalent to -273.15 degrees Celsius
High Specific Heat
Takes longer to heat up
Low Specific Heat
Heats up quickly
A cup of water 80 degrees C goes
Down to room temperature
Marble floor
Good Heat conductor
Carpet
Good insalator
Heat
The transfer of thermal energy from one object to another
Thermal Energy
Is caused by the internal motion of particles of matter and a form of kinetic energy
Cold particles
Move slower than warm particles
Heat Flows
from a warmer object to a cooler object
