Chapter 6 Flashcards
temperature
a measure of how hot (or cold) something is; specifically, a measure of the average kinetic energy of the particles in an object
Thermal Expansion
an increase in the size of a substance in response to an increase in the temperature of the substance
Absolute Zero
the temperature at which molecular energy is at a minimum (0 K on the Kelvin scale or -273.16 degrees on the Celsius Scale
Heat
the 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 1 K or 1 C in a specified way given constant pressure and volume
States of Matter
the physical forms of matter which include solid, liquid, and 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.
