One mole of a monatomic ideal gas is taken througlh a cycle ABCD as shown in the P-V diagram Column II gives the charctierstic involved in the cycle. Math them with each of the processes given in Column-I
`{:("Column"-I,"Column"-II),((A)"Process" A to B,(p)"Internal energy decreases"),((B) "Process" B to C,(q) "Internal energy incerease"),((C) "Process" C to D,(r)"Heat is lost"),((D) "Process" D to A,(s) "Heat is gained"),( ,(t) "Work is done on the gas"):}`

Answer

"(A)p,r,t(B)p,r(c)q,s(D)r,t"
