Which of the following processes must violate the first law of thermodynamics `(Q=W+DeltaE_(int))`?

Options

A. (a)`Wgt0 , Qlt0` and `DeltaE_(int)gt0`
B. (b)`Wgt0 , Qlt0` and `DeltaE_(int)lt0`
C. (c)`Wlt0 , Qgt0` and `DeltaE_(int)lt0`
D. (d)`Wgt0 , Qgt0` and `DeltaE_(int)lt0`

Answer

A, C

Explanation

For `(A): Wgt0` & `DeltaE_(int)gt0 implies Qgt0`
`(" ")` For `(B)`: `Wgt0` &`DeltaE_(int)lt0 implies Qgt 0` or `Qlt0`
For `(C): Wlt0`&`DeltaE_(int)lt0 implies Qlt0 " "` For `(D): Wgt0` & ` Delta E_("int")lt0 implies Qgt0 ` or `Qlt0`
