Heat Transfer Vocab
What is conduction?
The transfer of thermal energy between materials when touching due to particle collisons.
What is evaporation?
A substance changing from a liquid to a gas.
What is matter?
Anything that has mass or takes up space.
What is diffusion?
The movement of particles moving faster during a lower concentration.
What is heat?
The amount of thermal energy transferred from an area of higher temperature to an area of a lower temperature.
What is temperature?
The measure of the average kinetic energy of particles in a material.
What is a particle?
A small form of matter.
What is an insulator?
A material through which thermal energy does not flow easily;non-metals.
What is convection?
The transfer of thermal energy by the movement of particles from one part of a material to another.
What is potential energy? (Hint: 2 words)
Stored energy.
What is a liquid?
Material that does NOT have constant shape but constant volume.
What is deposition?
A substance changing from a gas to a solid.
What is radiation?
The transfer of thermal energy by the movement of particles from one part of a material to another by electromagnetic waves.
What is kinetic energy?
Energy of moving particles.
What is thermal expansion?
An increase in volume of a material caused by the particles moving faster during a temperature increase.
What is an open system?
Exchanges energy and matter with the envierment.
What is a closed system?
Does not exchange energy or matter with the environment.
What is sublimation?
A substance changing from a solid to a gas.
What is random motion?
Movement that occurs in all directions at different speeds.
What is a solid?
