Match the thermodynamic processes given under column I with the expressions given under column II.

Answer

A, B, C, D

Explanation

`(A) H_(2)O(l) rarr H_(2)(s)` at 273K. & 1 atm
`DeltaH =-ve =q`
`DeltaS_("sys") lt 0, DeltaG=0.`
`w ne 0` (as water expands on freezing ), `DeltaU ne 0`
(B) Free expansion of ideal gas. `" "q=0`
`w=0`
`DeltaU=0`
`DeltaS_("sys") gt 0`
`DeltaG lt 0`
(C) Mixing of equal volumn of ideal gases at constant pressure & temp in an isolated container
`q=0, w=0, DeltaU=0, DeltaS_("sys") gt 0, DeltaG lt 0`
`H_(2)(g)300K underset("Heating 1 atm") overset("Revesible") rarr 600 K underset("Cooling 1 atm") overset("Reversible")rarr 300 K .`
`q=0, w=0, DeltaU=0 , Delta=0 DeltaS_("sys") =0`
