Transfer of thermal energy

1. Conduction is transfer of thermal energy through a solid medium without the flow of the flow of the medium from a place of higher concentration to the place with lower concentration of thermal energy

1.1. Factors affecting conduction are Temperature difference. The greater the difference in temperature between the two ends of the bar, the greater the rate of thermal energy transfer, so more heat is transferred. ... Cross-sectional area. ... Length (distance heat must travel). ... Time.

2. Convection is the transfer of thermal energy in fluids by the help of convection currents caused due to the difference in density

2.1. Factors affecting convection are Temperature difference. The greater the difference in temperature between the two ends of the bar, the greater the rate of thermal energy transfer, so more heat is transferred. ... Cross-sectional area. ... Length (distance heat must travel). ... Time.

5. Radiation

5.1. Radiation is the transfer of thermal energy by the help of electromagnatic waves it can travel through vaccum

5.1.1. There are some factors affecting radiation. First there is appearance of the object. If the object is shiny and smooth it will reflect most of the radiation and absorb a very minor amount of radiation. If the object is black and rough it will absorb much more radiation. The next is the surface area of the object is the surface area of the object is large then it will absorb more radiation.
