Methods of Heat Transfer

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one through physical contact.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases). It occurs when warmer, less dense fluid rises and cooler, denser fluid sinks, creating a circulation pattern.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves. It does not require a medium to travel, allowing heat to be transferred through empty space.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance. It is related to temperature and the state of matter.

Front

What is an example of conduction?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of convection?

Back

An example of convection is the warm air rising from a heater and circulating around a room.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin.

Front

What is the difference between conduction and convection?

Back

Conduction involves direct contact between materials, while convection involves the movement of fluids to transfer heat.

Front

What is the role of thermal energy in weather patterns?

Back

Thermal energy drives weather patterns by causing air and water to move, leading to phenomena like wind, rain, and temperature changes.

Front

What is the significance of the Pacific Ocean currents?

Back

The hot and cold currents in the Pacific Ocean are examples of convection, which play a crucial role in regulating climate and weather patterns.
