Convection is heat flow by means of moving matter. It only works in fluids (i.e. liquids and gases).
Conduction is heat flow by means of direct physical contact.
Radiation is heat flow by means of electromagnetic waves. It can work through a vacuum.
Heat always naturally flows from something "hot" to something "cold". This is a form of entropy.

What is the difference between conduction and convection a 5th grade answer please?
Conduction occurs in solids and liquids but not gases. Convection occurs in gases and liquids.
What is the difference between conduction convection and thermal energy?
Conduction and convection are two ways in which thermal energy is transferred, the third way is by radiation.
What are the methods of heat transfer?
convection, conduction and radiation
What does conduction and convection need to work?
Heat energy and a temperature difference.
What is an energy transfer due to a difference in temperature?
conduction, convection or radiation
What is an energy transfer due to difference in temperature?
conduction, convection or radiation
What are the three forms of heat transfer?
convection conduction and radiation
What happens at each layer of the earth?
Conduction, Convection, Conduction,Convection, Conduction, Radiation
What is the difference between conduction and convection?
Conduction transfers heat by direct contact. Convection, is the transfer of heat by movement of the medium, due to difference of density caused by changes in temperature.
Is newt boiling in a hot cauldron convection conduction or radiation?
Conduction
What is the differ of conduction and convection?
conduction by itself is slower to heat but conduction and convection is faster to heat
What are 3 methods of heat transfer?
Heat (or thermal) energy is kinetic energy due to motion of atoms and molecules. It is energy that is in the process of being transferred from one object to another because of their temperature difference
