A broad question, so I will give a broad answer. A driving force is needed and what drives heat transfer is simply temperature differences between two bodies.
The mechanism at say a molecular level is really just the exchange of the energy from molecules to molecules. Higher energy molecules will collide with lower energy molecules and voila, you have heat transfer.

What are the advantages disadvantages of concentric tube heat exchanger?
Advantages: Simplicity of design; Easy to clean and maintain; ideal for fluids that cause fouling. Disadvantages: Length cannot be extended beyond a limit Rate of heat transfer is low + high cost when considering amt of heat transfer. Heat looses occur from the outer shell.
What is interfacial area?
when two material are brought to contact,so the space where they made contact is called interfacial area,it is usually considered in heat transfer calculation
How steam required for steam tracing of jacketed lines is calculated how much steam required for sulfur melting?
The steam required for steam tracing is calculated on the basis of the amount of heat transfer that is required or the temperature that you want to maintain with the help of steam. It also depends on the pipe material through which the steam is passing,the condition of the steam that whether it is saturated or superheated etc. Overall heat transfer cofficient is calculated considering all the factors like fouling or scaling,inside and outside dia. , surface area etc. After calculating the amount of heat to be transferred, the requirement of rate of steam is calculated. Generally, Low pressure steam is used as it has got more latent/Sensible heat as compared to MP or Superheated steam.
Can you major in chemistry and become a chemical engineer?
It is possible but would be tough for a person from chemistry background. This is since he has to go into the basic technical aspects such as fluid mechanics, heat transfer, engineering thermodynamics, calculus and process design without which a chemical engineer is impossible.
How do you manually add glycol to a commercial hot water system?
Pump it in while it is circulating and continually test the freeze point of the mix. If you make it too thick the solution will lose it`s heat transfer properties reducing system capacity. +10F is usually ok.
How heat transfer is controlled?
There is a special mechanism that controls heat transfer.
What is the heat transfer mechanism responsible for the daily wind cycle?
heat transfer through convection.
Which mechanism is not a way to transfer heat?
Fusible link
What is a mechanism of heat transfer that involves direct contact?
conduction
What is the least important mechanism of heat transfer in the whole atmosphere?
Conduction
What is the major heat transfer mechanism within solids?
conduction
Does slow movements of mantle rock called radiation transfer heat in the mantle?
You have the mechanism of heat transfer correct but the name for it incorrect! The process where slow movements of mantle rocks transfer heat is known as convection.
What type of heat transfer occurs between a pan and a hot stove burner the pan is sitting on?
The predominant heat transfer mechanism used to transfer heat from the pan to the stove burner is radiation.
What are the mechanism of heat transfer?
Radiation, conduction, and convection You may want to look on this website!
Mechanism of osmotic and heat transfer in vegetable?
i wanted to know the effect of the above question on vegetable
Distinguish between valence and conduction electron hence explain the mechanism of electrons heat and heat transfer in conduction?
Why is conduction important?
Does gas conduct convection of heat?
"Conduct" and "convection" are two different processes of heat transfer. When heat is transferred through a gas, the primary mechanism is convection.
