Thermal Energy Transfer

Front

What is convection in the context of thermal energy transfer?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

What type of heat transfer occurs when you walk on warm sand with bare feet?

Back

Conduction is the type of heat transfer that occurs when heat is transferred through direct contact between materials.

Front

In thermal energy transfer, heat moves from areas of ____ temperature to areas of ____ temperature.

Back

Heat transfers from areas of high temperature to areas of low temperature.

What are the three main types of thermal energy transfer?

Back

The three main types of thermal energy transfer are conduction, convection, and radiation.

Front

What happens to the particles of a substance as it heats up?

Back

As a substance heats up, its particles gain energy and speed up, leading to increased movement.

Front

Define conduction in thermal energy transfer.

Back

Conduction is the process of heat transfer through direct contact between materials, where energy is transferred from the hotter object to the cooler one.

Front

What is radiation in the context of thermal energy transfer?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur in a vacuum and does not require a medium.

Front

How does convection differ from conduction?

Back

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

Front

What role does density play in convection currents?

Back

Density differences in fluids create convection currents, as warmer, less dense fluid rises while cooler, denser fluid sinks.

Explain the concept of thermal equilibrium.

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature, resulting in no net heat transfer between them.
