Question 414: Thermodynamics & KTG

Question

Match the thermodynamic processes taking place in a system with the correct conditions. In the
table : $$\Delta $$Q is the heat supplied, $$\Delta $$W is the work done and $$\Delta $$U is change in internal energy of the
system.

Process
Condition

(I) Adiabatic
(1) $$\Delta $$W = 0

(II) Isothermal
(2) $$\Delta $$Q = 0

(III) Isochoric
(3) $$\Delta $$U $$ 
e $$ 0, $$\Delta $$W $$ 
e $$ 0,
 $$\Delta $$Q $$ 
e $$ 0

(IV) Isobaric
(4) $$\Delta $$U = 0

Accepted Answer

(I) Adiabatic, $$\Delta $$Q = 0
(II) Isothermal, $$\Delta $$U = 0
(III) Isochoric, $$\int {pdV} $$ = 0 $$ \Rightarrow $$ W = 0
(IV) Isobaric process $$ \Rightarrow $$ Pressure remains constant
W = P.$$\Delta $$V $$ 
e $$ 0
$$\Delta $$U $$ 
e $$ 0
$$\Delta $$Q = nC
p
$$\Delta $$T $$ 
e $$ 0
