Interpretation Introduction

Interpretation:

From the given set of thermodynamic functions, the functions that is associated with the first law thermodynamics has to be found.

Concept Introduction:

According to first law of thermodynamics the total energy of the universe is constant.  Energy can only be transferred from one form to another, cannot be prepared or destroyed.  The first law can be mathematically represented as given below.

  $\text{ΔU = q + w}$

Where,

  $\text{ΔU}$ is the change in internal energy

  $\text{q}$ is the heat added to the system

  $\text{w}$ is the work done on the system
