Heat does not exist at the level of atoms, at the level of the atom its kinetic energy; which is only observed as heat at the macroscopic/bulk level.
Atoms with more kinetic energy bounce harder against other atoms, transferring more kinetic energy to those atoms. This has two effects at the macroscopic/bulk level, where heat is observed:
- direct transfer of kinetic energy results in diffusion of heat, called conduction
- kinetic energy pushes the atoms further apart causing a reduction in density, enabling a process called convectionif the liquid is accelerating or in a gravitational field

Transfer of heat by hot liquids and gases?
Convection is the transfer with in the fluid. If a container of hot liquid is touching something then it is conduction. If the heat is travelling through the air then it is radiation.
What fluid instead of water can be used as a heat transfer in domestic heating system?
Liquid sodium
What does convection mean in science terms?
convection is the transfer of heat in a liquid or gas by thermal energy from one part of a fluid to another. ;0)
What is a thermal conduction?
heat transfer from one molecule to another -apex
What method of heat transfer is known as conduction?
No,the transfer of heat by the movement of heated fluid is called convection.
What is the heat which travel molecule to molecule?
if you mean the transfer rate of heat ?; the heat transfer rate depends on the atom or molecule type .
What is the transfer of heat by a liquid or gas?
convection
What is the transfer of heat within a liquid?
when the temperature of the liquid is the same throughout.
What does Heat transfer by convection requires to transfer heat?
A liquid - - - which changes density when heated, and A gravity field.
What is the term for heat transfer because of the heat of gas?
Convection is the transfer of heat through the movement of a fluid, whether liquid or gas.
How does Transfer of heat energy in a liquid?
conduction and convection (which requires a circulation of the liquid).
What effect does the transfer of heat have on the particles of water?
The transfer of heat in the water and in other liquid takes place by the movement of Molecules from the source of heat to the other part of liquid.This results the Boiling in the liquid.
What is the transfer of heat by the motion of liquid and gasses?
CONVECTION
Heat convection what is?
Convection is the transfer of heat by circulation through a gas or liquid.
What is heat convection?
Convection is the transfer of heat by circulation through a gas or liquid.
Is conduction a heat transfer by direct contact of particles of matter?
Yes, whereas convection heat transfer is the transfer of heat via a liquid, and radiative heat transfer occurs through empty space (like the heat you feel from the sun).
What type of heat transfer uses a gas or a liquid to transfer the heat?
Conduction AND convection, only the latter requires a fluid.
