Question

In a steady state process, which of the following quantity remains constant throughout the process

• A. Enthalpy
• B. Entropy
• C. Temperature and heat both
• D. Internal energy

Answer 1

The correct option is D Internal energy

A steady state is a state which remains the same over given time period. In heat transfer problems if there is specific rate of heat transfer through medium (for conduction or convection) and if it remains constant at any time then it is said to have steady state heat transfer. In steady state, there may be different temperatures in body at different locations but the temperature at any given point will remain constant. If the temperature at all locations is same then it is uniform.

n a steady state process, Internal energy is quantity remains constant throughout the process
