WebMar 26, 2016 · Here are the factors that affect the rate of conduction: 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. The heat, Q, is proportional to the difference in temperature: Cross-sectional area. WebA is the surface area of the ice cube or ice block. ΔT is the temperature difference between ice surface and ambient air. In the above equation, U and ΔT are the same in case of ice cube and ice block. Only the surface area is different. It is quite clear then, the the rate of heat transfer is directly proportional to the surface area of the ...
