A body X at an original temperature 100^(@)C and another body at an original temperature 0^(@)C and placed in an evacuated conclosure, the walls of which are maintained at 10^(@)C. Which one of the following statementis consistent with Prevost's theory ?

Answer»

X EMITS but does not ABSORB heat
Y absorb but does not emit heat
The final temperature of the bodies will be the MEAN of their initial temperature (i.e., `50^(@)C`)
The walls of the enclosure RADIATE heat to both X and Y

Solution :`n = 1`
`P = "constant"`
`V_(1) = V, V_(2) = 2V, T_(1) = T`
`W = PDeltaV = P(2V - V) , T_(2) = 2T`
`W = PV = nRT = RT`
