Can the absolute value of internal energy be determined ? Why or why not ?

Explanation

To answer the question, "Can the absolute value of internal energy be determined? Why or why not?", we can follow these steps:

### Step 1: Understanding Internal Energy
Internal energy (U) is defined as the total energy contained within a system. It includes various forms of energy such as kinetic energy, potential energy, electronic energy, and molecular configuration energy.

### Step 2: Absolute Value of Internal Energy
The absolute value of internal energy refers to a specific numerical value of U that is independent of any reference point. However, internal energy is a state function, and its absolute value cannot be determined directly.
