IScience - Chapter 6 Vocab Flashcards
Thermal Energy
The sum of the kinetic energy and the potential energy of the particles that make up a material
Temperature
Represents the average kinetic energy of the particles that make up a material
Heat
The movement of thermal energy from a warmer object to a cooler object
Radiation
The transfer of thermal energy from one material to another by electromagnetic waves
Conduction
The transfer of thermal energy between materials by the collisions of particles
Thermal Conductor
A material through which thermal energy flows easily
Thermal Insulator
A material through which thermal energy does not flow easily
Specific Heat
The amount of thermal energy required to increase the temperature of 1 kg of a material by 1 degree Celsius.
Thermal Contraction
A decrease in a material’s volume when its temperature decreases
Thermal Expansion
An increase in a material’s volume when its temperature increases
Convection
The transfer of thermal energy by the movement of particles from one part of a material to another. (Only occurs in fluids)
Convection Current
The movement of fluids in a cycle because of convection
Heating Appliance
A device that converts electric energy into thermal energy
Thermostat
A device that regulates the temperature of a system
Refrigerator
A device that uses electric energy to transfer thermal energy from a cooler location to a warmer location
