Transfer of Thermal Energy Flashcards
1
Q
How does thermal energy flow?
A
From a region of higher temperature to a region of lower temperature.
2
Q
What is conduction?
A
The process by which thermal energy is transmitted through a medium from one particle to another without any flow of medium.
3
Q
What is convection?
A
The process by which thermal energy is transmitted from one place to another by the movement of heated gas or liquid due to a difference in density.
4
Q
What is radiation?
A
The process by which thermal energy is transmitted by electromagnetic waves.
5
Q
What are the factors affecting rate of radiation?
A
Surface temperature, surface colour and texture, surface area
