Convection as a form of heat transfer occurs whenever something is hotter than the air around it.

An example might be a stove-top that has been turned on or asphalt in the sun.

2 What materials allow convection to take place?

Materials that allow convection to take place are usually fluids or gases, as they can easily move and transfer heat through the process of convection. Solids can also participate in convection to a lesser extent, especially if they have some degree of flexibility or ability to transmit heat through them. In general, materials that can move or flow are more likely to enable convection.

What is needed for conduction and convection to take place but not radiation?

Conduction and convection require a medium, such as solids or fluids, to transfer heat through direct contact or movement. Radiation, on the other hand, can occur in a vacuum or through empty space as electromagnetic waves. So, for conduction and convection to take place but not radiation, a medium for heat transfer is necessary.


Why can convection of current not take place when solids are heated?

Convection requires the movement of a fluid medium to transfer heat. Since solids do not have the ability to flow like liquids or gases, convection of current cannot take place in solids when they are heated. Heat can still be transferred through conduction in solids, where it is transferred from one molecule to another through direct contact.


What are the Examples Between Conduction And Convection?

An example of conduction is when a metal spoon in a hot drink gets hot at the handle end. An example of convection is when warmer air rises, causing cooler air to move in and take its place, creating a convection current.
