Radiation

Radiation is the transfer of heat through electromagnetic waves. These waves can travel through a vacuum, which is why radiation can occur in space.

There are three types of radiation:

• Thermal radiationis emitted by all objects with a temperature above absolute zero.
• Solar radiationis emitted by the sun.
• Cosmic radiationis emitted by stars and other celestial objects.

Sources of radiation include:

• The sun
• Stars
• Nuclear reactors
• Medical imaging devices

Convection

Convection is the transfer of heat through the movement of fluids. Fluids can be liquids or gases.

There are two types of convection:

• Natural convectionoccurs when a fluid is heated or cooled, causing it to expand or contract. This change in density causes the fluid to move, transferring heat.
• Forced convectionoccurs when a fluid is forced to move by an external force, such as a fan or pump. This type of convection is often used to cool electronic devices.

Examples of convection currents include:

• The circulation of air in a room
• The movement of water in a pot of boiling water
• The flow of lava in a volcano

Conduction, Radiation convection and conduction worksheet

Conduction is the transfer of heat through direct contact between two objects. The rate of heat transfer depends on the temperature difference between the objects and the material properties of the objects.

There are two types of conduction:

• Metallic conductionoccurs in metals, which are good conductors of heat.
• Non-metallic conductionoccurs in non-metals, which are poor conductors of heat.

Examples of materials that are good conductors of heat include:

• Metals (e.g., copper, aluminum, steel)
• Graphite
• Water

Examples of materials that are poor conductors of heat include:

• Wood
• Plastic
• Rubber

Key Questions Answered: Radiation Convection And Conduction Worksheet

What is the difference between radiation, convection, and conduction?

Radiation involves the transfer of heat through electromagnetic waves, while convection involves the transfer of heat through the movement of fluids, and conduction involves the transfer of heat through direct contact between objects.

What are some examples of radiation in everyday life?

Examples of radiation include sunlight, heat from a fire, and X-rays.

What are some applications of convection in industry?

Convection is used in heating and cooling systems, such as radiators and air conditioners, as well as in industrial processes such as drying and evaporation.
