The gases become denser at …A… Here, A refers to — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

I notice the question is incomplete—the options (A, B, C, D) and the context about "gases become denser" are not provided in your query. However, based on typical JEE/NEET chemistry questions about gas density, the answer **C** likely refers to one of these common scenarios: **If the question is:** "Gases become denser at…" **Most probable contexts:** 1. **Lower temperature & higher pressure** – Gas density increases with ↓T and ↑P using $\rho = \frac{PM}{RT}$ 2. **Higher pressure** – Boyle's Law: density ∝ pressure at constant temperature 3. **Lower temperature** – Charles's Law: density ∝ 1/temperature at constant pressure 4. **Critical point region** – Gases approach liquid-like density **General reasoning:** From the ideal gas equation: $PV = nRT$, we get density $\rho = \frac{PM}{RT}$ - Density ↑ when P ↑ (compression) - Density ↑ when T ↓ (cooling) **Please provide the complete question with options A, B, C, D so I can give you the precise explanation for why C is correct.**
