Chapter 13 Temperature And Energy Flashcards
Temperature
A measure of how hot or cold something is or the amount of average kinetic energy of particles in an object
Thermometer
Instrument that indicates temperature
Absolute zero
When the temperature reaches the minimum molecular energy (0 K on the Kelvin scale or -273.16 degrees C on Celsius scale)
Heat
Energy transferred between objects at different temperatures
Thermal conduction
The transfer of energy as heat moves through a material
Convection
Movement of matter because of different densities that are caused by temperature variations
Convection current
The vertical movement of air currents due to the temperature variations
Radiation
The energy that is transferred as electromagnetic waves including visible light and infrared waves
Specific heat
A quantity of her needed to raise a unit mass of homogenous material; 1 K or 1 degree C in a specified way given constant pressure and volume
Electromagnetic waves
Energy that is transferred as heat from an object
Infrared radiation, visible light, and ultraviolet rays
Conductor
My material in which energy can be easily transferred as heat
Insulator
Poor/ bad conductors used to reduce energy transfer
Refrigerant
Causes cooling
Heat engine
A device that produces power from heat
Gasoline engine or steam engine
