One natural example of convection currents is wind. As the Sun shines down on an area of land, it heats the air above the ground. That warm air rises. As it rises, cooler air moves in to take the place at the bottom.

Everyday Examples of Heat or Thermal Conduction

• After a car is turned on, the engine becomes hot.
• A radiator is a good example of conduction.
• You can warm your back muscles with a heating pad.
• Roasting wieners over a campfire is fun until the heat from the fire is conducted up the coat hanger to your hand.

Which statement is true about radiation? Radiation is the transfer of heat through electromagnetic waves. Which situation best represents conduction? Touching a hot piece of metal.

If it’s a hot day and you touch any metal on a car, you might suffer a burn. This happens through conduction. If you feel a warm breeze, this is through convection. But sunburn is caused by ultraviolet radiation from the sun.

There are three basic ways in which heat is transferred: convection, conduction and radiation. A campfire is a perfect example of the different kinds of heat transfer. If you boil water in a kettle, the heat is transferred through convection from the fire to the pot.

A fire spreads by transferring heat energy in three ways: Radiation, Convection, and Conduction. Radiation refers to the emission of energy in rays or waves. Heat moves through space as energy waves. As the fire front gets closer, the amount of radiant heat received is increased.

Wood burning fires transfer heat in the same way as many modern heating appliances. These include convection, which is a transfer of heat through air currents. Conduction is a transfer of heat through solid objects such as the ground or the bricks in a fireplace wall.

Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated. As a result, the particles take up more volume.

Convection occurs through the movement of particles. As particles become heated, the molecules move faster and faster, and as molecules move apart, density decreases. The warmer, less dense material rises compared to the surrounding cooler, higher density material.
