Dry ice on heating produces

Options

A. liquid `CO_(2)`
B. liquid water
C. gaseous `CO_(2)`
D. water vapour

Explanation

### Step-by-Step Solution:

1. **Identify Dry Ice**:
- Dry ice is the solid form of carbon dioxide (CO2).

2. **Understand the Process of Heating**:
- When dry ice (solid CO2) is heated, it undergoes a physical change.

3. **Sublimation Process**:
- Sublimation is the process where a solid changes directly into a gas without passing through the liquid phase.

4. **Heating Dry Ice**:
- Upon heating, dry ice sublimates, meaning it transitions from solid CO2 directly to gaseous CO2.

5. **Conclusion**:
- Therefore, when dry ice is heated, it produces gaseous carbon dioxide (CO2).

### Final Answer:
Dry ice on heating produces gaseous carbon dioxide (CO2).
