thermal energy science Flashcards
Thermal (energy)
The total kinetic (motion) energy of tiny particles that make up matter. The faster the particles move, the warmer the matter becomes.
Temperature
Average kinetic energy of all the particles of a material; it is measured with a thermometer in degrees (usually
Heat transfer
The flow of thermal energy depending on the nature of the matter, the size of the sample, and the temperature of the environment.
Fahrenheit
A temperature scale, used largely in the USA, which states that water freezes at 32 degrees F and boils at 212 degrees F
Celsius
The scale of temperature in which water freezes at 0° and boils at 100° under standard conditions.
Kelvin
the SI base unit of thermodynamic temperature, equal in magnitude to the degree Celsius.
conduction
transfer of thermal energy by contact
convection
transfer of thermal energy by currents
Radiation
the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization
Solid
A state of matter with definite volume and shape.
Liquid
A state of matter with a definite volume, but no definite shape.
Gas
A form of matter with indefinite shape and volume
Conductor
a material or device that conducts or transmits heat, electricity, or sound, especially when regarded in terms of its capacity to do this
Insulator
prevents the transfer of thermal energy
Conservation of Energy
can not be created or destroyed but can be altered to another form
