Chapter 10. Section 1-4 Flashcards
Thermal Expansion
An increase in the size of a substance in response to an increase in the temperature of the substance
Temperature
Measure of the average kinetic energy of the particles in an object
Absolute Zero
the temperature at which molecular energy is at a minimum
heat
energy transferred between objects that are at different temperatures
thermal energy
the kinetic energy of a substance’s atoms
thermal conduction
the transfer of energy as heat through a material
thermal conductor
a material through which energy can be transferred as heat
thermal insulator
a material that reduces or prevents the transfer of heat
convection
the transfer of thermal energy by the circulation or movement of a liquid or gas
radiation
the transfer of energy as electromagnetic waves
specific heat
the quantity of heat required to raise a unit mass of homogeneous material
states of matter
the physical forms of matter, which include solid, liquid, gas
change of state
the change of a substance from one physical state to another
insulation
a substance that reduces the transfer of electricity, heat, or sound
heat engine
a machine that transforms heat into mechanical energy, or work
