In this question, I guess the empires, theaters as well as the aqueducts, stadiums and roads were all built by d. slaves. I am not sure but hope this is the right answer and would be of big help then.
Thermal energy can be transferred in three main ways which are:
- Conduction - transfer when bodies are touching.
- Convection - transfer of heat in liquid or gas.
- Radiation - transfer of heat through space.
<h3>How is thermal energy transferred?</h3>
The first method is through conduction where heat spreads from one object to another object it is touching.
Convection involves heat being transferred in liquid or gas while radiation allows heat to move through space like the sun warming the earth.
