According to Prevost theory of heat exchange

Question

RRB Paper · Accepted Answer

Prevost's theory of exchanges stated that each body radiates to, and receives radiation from, other bodies. The radiation from each body is emitted regardless of the presence or absence of other bodies. According to the Prevost theory of heat exchange, Every material body, at any temperature above absolute zero, radiates heat to the surroundings and at the same time absorbs heat from the surroundings.

According to Prevost theory of heat exchange

It is impossible to transfer heat from low temperature source to t high temperature source

Heat transfer by radiation requires no medium

All bodies above absolute zero emit radiation

Heat transfer in most of the cases takes place by combination of conduction

convection and radiatio

The correct answer is `No. 3: All bodies above absolute zero emit radiation`
