Question 353: Thermodynamics & KTG

Question

Three different processes that can occur in an
ideal monoatomic gas are shown in the P vs V
diagram. The paths are labelled as A $$ 	o $$ B,
A $$ 	o $$ C and A $$ 	o $$ D. The change in internal
energies during these process are taken as
E
AB
, E
AC
and E
AD
and the work done as W
AB
,
W
AC
and W
AD
.
The correct relation between these parameters
are :

Accepted Answer

For all process,
E
AB
= E
AC
= E
AD
W
AB
> 0 as volume increases.
W
AC
= 0 as volume constant.
W
AD
< 0 as volume decreases.

Answer

E AB < E AC < E AD , W AB > 0, W AC > W AD

Answer

E
AB
= E
AC
= E
AD
, W
AB
> 0, W
AC
= 0, W
AD
< 0

Answer

E AB > E AC > E AD , W AB < W AC < W AD

Answer

E
AB
= E
AC
< E
AD
, W
AB
> 0, W
AC
= 0, W
AD
< 0
