Chemical Engineering > GATE 2017 > Enthalpy Change
Water is heated at atmospheric pressure from 40°C to 80°C using two different processes. In process I, the heating is done by a source at 80°C. In process II, the water is first heated from 40°C to 60°C by a source at 60°C, and then from 60°C to 80°C by another source at 80°C. Identify the correct statement.
A
(A) Enthalpy change of water in process I is greater than enthalpy change in process II
B
(B) Enthalpy change of water in process II is greater than enthalpy change in process I
C
(C) Process I is closer to reversibility
D
(D) Process II is closer to reversibility

Correct : d
