Convection is the transfer of heat via the movement of warmer material nearest a source of heat toward colder regions, while colder material moves toward the heat source. Usually, the warmer material moves upward from the heat source (since "heat rises") and then is pushed outward toward colder regions, setting up a circulating current that pushes the colder material sinks downward and toward the heat source.
Unlike conduction (where heat is transferred by direct contact with the heat source) or radiation (where the heat source sends out waves of heat), convection requires a circulating "current" -- where material moves or flows within a fluid, such as a liquid or gas. This flow is not possible within a solid -- where the material inside cannot move from place to place.
Convection cannot occur in a vacuum, either, since there is no material to flow from one place to another.
What else can I help you with?
Can heat transfer by convection happen in a solid?
No, heat transfer by convection requires the movement of fluids to transfer heat. Since solids do not have the ability to flow like fluids, heat transfer by convection does not typically occur in solids. Heat transfer in solids usually occurs through conduction, where heat is transferred through the vibration of particles.
Why doesn't convection happen in solid?
Convection requires the movement of a fluid, such as liquid or gas, to transfer heat. In a solid, the particles are tightly packed and cannot easily flow or move past each other to carry heat through convection. As a result, convection does not occur in solids.
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.
Why can't heat be transferred by convection in solids?
Heat cannot be transferred by convection in solids because convection involves the movement of a fluid due to temperature differences, but solids do not flow like fluids. In solids, heat is primarily transferred through conduction, where the heat is passed from one particle to another through direct contact.
What substances can convection happen in?
Convection can occur in fluids such as water and air, as well as in some solids like magma and hot metals. This process involves the transfer of heat through the movement of fluid particles due to differences in temperature and density.
Can heat transfer by convection happen in a solid?
No, heat transfer by convection requires the movement of fluids to transfer heat. Since solids do not have the ability to flow like fluids, heat transfer by convection does not typically occur in solids. Heat transfer in solids usually occurs through conduction, where heat is transferred through the vibration of particles.
Is convection a chemical reaction?
no it is a type of conduction that can happen in liquids and gases, conduction happens in solids, and radiation happens in gases

Heat convection does not occur in solids because?
Because the atoms do not move around. The whole idea of convection is that 'groups' of things move about. In the case of heat convection these moving groups take or bring their heat with them.
Why convection currents can be set up in liquids and gases but not in solids?
Matter doesn't move easily in solids.
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.
How does heat flow in solids and fluids?
Either by conduction or convection?
How energy transferred through convection?
by The movement of heated particles of a gas or a liquid. convection cannot take place in solids because solids have fixed shape. particles like Pizza
Why can't heat be transferred by convection in solids?

Why convection cannot take place in solids?
Convection relies on the movement of fluid particles, such as air or water, to transfer heat. Since solids do not have freely moving particles like fluids, convection cannot take place within them. Heat transfer in solids typically occurs through conduction, where heat is transferred through the vibration of atoms or molecules.
What is heat transfer by convection possible only in liquids and gases?
Because convection occurs by convection currents. Convection currents occur as a result of the movement of a body. Since solids cant move, convection only occurs in fluid, i.e., liquids and gases
