Heat

Heat is the movement of thermal energy from a warmer object to a cooler object.

Kinetic Energy

the energy an object has due to its motion or movement

Temperature

A measure of the average kinetic energy of an object’s particles

Thermal Energy

The total kinetic and potential energy of all the particles of an object.

Conduction

Transfer of thermal energy by direct contact of two objects or portions of matter

Thermal Conductor

Substances that thermal energy can easily move through

Thermal Insulator

Substances that thermal energy cannot move through

Convection

A type of thermal energy transfer in which currents carry thermal energy from one part of the fluid to another

Energy Transfer

The process of moving energy from one place to another, or from one object to another

Radiation

The process of thermal energy transfer by electromagnetic waves

Heat Transfer

The transfer of thermal energy from a warmer object to a cooler object.

Thermal Equilibrium

State in which all parts of a system are at the same temperature

Thermal Expansion

Tendency of particles to spread out when the kinetic energy increases

Guiding ?s

TEKS-based questions that students should be able to answer as a result of mastering the standards for this unit

• How are temperature and kinetic energy of particles related?
• What happens to the particles of a substance when the temperature increases?
• What is thermal energy, and how does it move from one place to another?
• What is conduction, and how does it transfer thermal energy?
• What is convection, and how does it work to transfer thermal energy?
• What is radiation, and how does it differ from conduction and convection?
• Can you think of other examples of
• thermal energy transfer through radiation?
• What is meant by the term "thermal equilibrium"?
• What is thermal energy, and how does it flow between objects or substances?
• Why does thermal energy always move from warmer objects to cooler ones?
