Plot a graph between internal energy U and Temperature (T) of an ideal gas.

Explanation

To plot a graph between internal energy (U) and temperature (T) of an ideal gas, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Relationship**:
- For an ideal gas, the internal energy (U) is directly proportional to the temperature (T). This relationship can be expressed mathematically as:
\[
U = nC_vT
