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.
Why convection occurs only the liquid s and gases only but not in solids?
The molecules in solids are not free to move around as they are in liquids and gasses. It's the movement of the molecules that creates the convection currents.
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
Can waves transfer energy through liquids and solids but not through gases or empty space?
Some waves can transfer energy only through liquids and solids, but not through gases or vacuum. Some waves, like sound waves, can transfer energy through gases, liquids and solids but not through vacuum. And some waves, notably electromagnetic waves, can transfer energy through vacuum as well as matter.
Heat convection occurs in gases and liquids Heat convection does not occur in solids because solids are unable to?
transfer heat by fluid motion

Is it true that the pipettes are used to transfer solids from one container to another?
Transfer pipettes, also called Pasteur pipettes, are used to transfer small quantities of liquid from one container to another. They cannot be used to move a specific volume, they are just used for approximations. The only time they would be used to transfer solids would be solids suspended in a liquid solution.
What are the types of heat transfers?
Conduction: Transfer of heat in solids Convection: Transfer of heat in liquid and gases (convection currents are the motion of which the heat travels in, see hot air balloon's) Radiation: Transfer of heat through vacuum (space i.e no particles)
Why convection currents can be set up in liquids and gases but not in solids?
Matter doesn't move easily in solids.
The direct transfer of molecular motion through solids?
The direct transfer of molecular motion through solids is called conduction
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..

What is the transfer of energy between solids?
Conduction
What is Transfer of energy between solids?
Conduction
Can heat be conducted through solids?
Yes... the transfer of energy via the vibrating molecules of solids.....
What can people do to create sounds?
Anything that creates vibrations in solids and fluids.
