Q. According to Prevost theory of heat exchange (Solved)
1. it is impossible to transfer heat from low temperature source to t high temperature source
2. heat transfer by radiation requires no medium
3. all bodies above absolute zero emit radiation
4. heat transfer in most of the cases takes place by combination of conduction, convection and radiation
5. rate of heat transfer depends on thermal conductivity and temperature differenc
- c. all bodies above absolute zero emit radiation
