Problem
When 1 mol gas is heated at constant volume, temp. is raised from 298 to 308 K. Heat supplied to the gas is 500 J. Then which statement is correct :- (1)
q
=
w
=
500
J
q = w = 500\text{J}
q
=
w
=
500
J
,
Δ
U
=
0
\Delta U = 0
Δ
U
=
0
(2)
q
=
Δ
U
=
500
J
q = \Delta U = 500\text{J}
q
=
Δ
U
=
500
J
,
w
=
0
w = 0
w
=
0
(3)
q
=
w
=
500
J
q = w = 500\text{J}
q
=
w
=
500
J
,
Δ
U
=
0
\Delta U = 0
Δ
U
=
0
(4)
Δ
U
=
0
\Delta U = 0
Δ
U
=
0
,
q
=
w
=
−
500
J
q = w = -500\text{J}
q
=
w
=
−
