Chapter 6- Heat and Heat Technology 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 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 atom’s.
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 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.
