What is an example of:

a) radiation
b) conduction
c) convection

radiation: the heat of the sun.
conduction: heat one end of a metal tube and the other end will become hot due to conduction.
convection: hot air rises in a room and cold air moves from high to low. The cycle is called convection.

Thanks. :)

You're welcome! Here are examples of each:

a) Radiation: An example of radiation is the heat of the sun. When the sun emits electromagnetic waves, including infrared radiation, these waves travel through space and reach the Earth, providing heat and light.

b) Conduction: An example of conduction is when you heat one end of a metal tube. The heat energy is transferred through direct contact between the hot end and the molecules of the metal. As a result, the heat is conducted along the length of the tube, and eventually, the other end of the tube becomes hot.

c) Convection: An example of convection is when you observe how hot air rises in a room. As the air near a heat source (such as a radiator) gets heated, it becomes less dense and rises. This creates a movement of air, where the warmer air rises and displaces the cooler air above it. This cycle of warm air rising and cool air sinking is called convection.

Understanding these examples helps to grasp the principles behind each mode of heat transfer. Radiation involves the transfer of heat through electromagnetic waves, conduction occurs through direct contact between objects, and convection involves the movement of fluid (such as air or liquid) to transfer heat.
