Heat transfer flashcard

Front

What is the process responsible for the transfer of heat in liquids and gases?

Back

Convection

Front

Define convection in the context of heat transfer.

Back

Convection is the transfer of heat through the movement of fluids due to temperature differences.

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy between physical systems.

Front

Provide an example of convection in everyday life.

Back

A pot of water boiling on the stove.

Front

What are the three main modes of heat transfer?

Back

Conduction, convection, and radiation.

Front

How does convection differ from conduction?

Back

Convection involves the movement of fluids, while conduction is the transfer of heat through direct contact between materials.

Front

What role does temperature difference play in convection?

Back

Temperature difference drives the movement of fluids, causing warmer, less dense fluid to rise and cooler, denser fluid to sink.

Front

What is the significance of convection currents in the atmosphere?

Back

Convection currents help distribute heat in the atmosphere, influencing weather patterns and climate.

Front

In which state of matter does convection primarily occur?

Back

Convection primarily occurs in liquids and gases.

Front

What is an example of convection in the ocean?

Back

Ocean currents are an example of convection, where warm water rises and cold water sinks.
