thermal energy Flashcards
thermal energy
a rise in temperature causes atoms and molecules to move faster and collide with each other.
Temperature
how hot or cold something is
heat transfer
the movement of thermal energy from one thing to another thing of different temperatures.
Fahrenheit
the scale of temperature.
Celcius
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.
solid
firm and stable in shape; not liquid or fluid.
Conduction
the process by which sound waves travel through a medium
Convection
the movement caused within a fluid by the tendency of hotter
Radiation
the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization
liquid
a substance that flows freely but is of constant volume
gas
a substance or matter in a state in which it will expand freely to fill the whole of a container, having no fixed shape
conductor
a conductor is an object or type of material that allows the flow of charge
insulator
An electrical insulator is a material whose internal electric charges do not flow freely
conservation of energy
the law of conservation of energy states that the total energy of an isolated system remains constant
