Chapter 6 Flashcards
Thermal expansion
An increase in the size of a substances in response to an increase in the temperature of the substances
Absolute zero
The temperature at which molecular energy is at a minimum
Heat
The energy transferred between objects that are at different temperatures
Thermal energy
The kinetic energy of a substances atom
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 degree c I’m a specified way given constant pressure and volume
States of matter
The physical forms of matter which include solid liquid and gas
Insulation
A substance that reduces the transfer of electricity heat or sound
Heat engine
A machine that transforms hear into mechanical energy or work
Thermal pollution
A temperature increase in a body of water that is caused by human activity and that has a harmful effect on water quality and on the ability of that body of water support life
temperature
A measure of how hot or cold something is specifically a measure of the average kinetic energy of the particles in an object
