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.

Do Solids usually conduct heat better then liquids and gases?
Solids do conduct heat better than gases, although not necessarily better than liquids. Some solids are actually composite materials, because they can have a porous structure which contains gas within the solid, and this results in solids that do not conduct heat very well. But it is the gas component which has this insulating property.
How are humidity and convection connection?
Humidity and convection are connected because they both use heat to manipulate and change what is around them that causes a form of a reaction to occur.
How does heat travel in solids and liquids?
a. condensation b. conduction c. convection d. radiation
Where does convection occur?
Convection occurs when and where a fluid is in a gravity field and heat is applied to its base.
Why does conduction work best in solids?
It would be wrong to state that condution does not occur in liquids but yes the solids are better conductors because of the presence of more number of free electrons especially in the case of metals and also because of their crystal lattice structure.
Heat convection occurs in gases and liquids Heat convection does not occur in solids because solids are unable to?
transfer heat by fluid motion
When Heat convection occurs in gases and liquids heat conviction does not occur in solids because solids are unable to?
..to flow as easily. A malleable (space between particles) structure is need for convection to take place.
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
Why can't heat be transferred by convection in solids?
Because the molecules of a solid do not move [much] from their location.
Allows convection and can be a good conductor of heat?
Do Solids usually conduct heat better then liquids and gases?

But it is the gas component which has this insulating property.
How does heat flow in solids and fluids?
Either by conduction or convection?
Does convention occurs in solids?
Convection of mass cannot take place in solids, since neither bulk current flows nor significant diffusion can take place in solids. Diffusion of heat can take place in solids, but is referred to separately in that case as heat convection.
Why can heat travel through space by radiation but not by conduction or convection?
Because conduction and convection require particles to transfer heat. Space is a vacuum (has no particles in it) so convection and conduction cannot occur.
How does heat loss occur?
It can occur through conduction, convection and radiation.
By which mode of heat transfer heat is transferred in solids?
the process of transfer of heat energy in solids is known as conduction.. For more info-- the process of transfer of heat energy in liquids and gases is known as convection.. And the process of transfer of heat energy without any material medium is known as radiation..
Why convection cannot take place in solids?
because the process requires the formation of currents which is only possible in fluids (i.e solids and liquids). It is not possible for currents to develop in solids for the simple reason that the molecules in a solid are not free to move around and they are contained in their fixed positions.
