Real gases behave ideal at ........and .......

Explanation

To answer the question "Real gases behave ideal at ........ and .......", we need to identify the conditions under which real gases approximate ideal gas behavior.

### Step-by-Step Solution:

1. **Understanding Ideal vs. Real Gases**:
- Ideal gases are hypothetical gases that follow the ideal gas law (PV = nRT) perfectly under all conditions. They have no intermolecular forces and occupy no volume.
- Real gases, however, have intermolecular forces and occupy space, which causes deviations from ideal behavior, especially at high pressures and low temperatures.
