Unit 5 - Thermal Energy

Heat

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

the energy an object has due to its motion or movement

Kinetic Energy

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

Temperature

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

Thermal Energy

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

Conduction

Substances that thermal energy can easily move through

Thermal Conductor

Substances that thermal energy cannot move through

Thermal Insulator

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

Convection

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

Energy Transfer

The process of thermal energy transfer by electromagnetic waves

Radiation

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

Heat Transfer

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

Thermal Equilibrium

Tendency of particles to spread out when the kinetic energy increases

Thermal Expansion

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?
