Give the limitations of the first law of thermodynamics.

Explanation

**Step-by-Step Solution:**

1. **Understanding the First Law of Thermodynamics**: The first law of thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another. It emphasizes the conservation of energy in thermodynamic processes.

2. **Identifying Limitations**: While the first law is fundamental, it has certain limitations that need to be acknowledged.

3. **First Limitation - Spontaneity**: The first limitation is that the first law does not provide information about whether a process is spontaneous or not. A spontaneous process occurs naturally without external influence, and the first law does not indicate if energy transformations will occur spontaneously.
