The thermal conductivity and temperature difference between the surrounding and the entity plays a vital role in thermal energy transfer between the materials.
What is Thermal energy concept ?
The concept of thermal energy transfer involves the mode of transfer of heat energy from one particle to another.
Considering the three modes of heat transfer that are conduction, convection and radiation, each of these considers two major variables that includes :
- Temperature difference
- Thermal conductivity
The two scientific questions based on the above properties are given as follows:
1. A graphite sheet at 298 K and 0.5 cm thickness radiates some amount of heat when exposed to a temperature of 313 K. Calculate the heat flux.
2. 500 J of heat is passed through an rectangular aluminum sheet of thickness 5 mm. Calculate the temperature difference between the surrounding and the sheet.
Thus, we can conclude that thermal energy transfers accounts for different ways of transferring the heat energy between the entities. These methods considers temperature difference and thermal conductivity as prime variables.
