Insulation
A substance that reduces the transfer of electricity, heat, or sound.
Heat engine
A machine that transforms heat 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 to 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.
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 -2173.16 degrees C 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 degrees C in a specified way given constant pressure and volume.
States of matter
the physical forms of matter, which include solid,liquid, and gas.
