तापमान

Pressure
दबाव

Density $\rho = \frac{m}{V}$ . Using the ideal gas law $PV = nRT$ , and substituting $n = \frac{m}{M}$ (mass/molar mass), we get:

$\rho = \frac{PM}{RT}$

Thus, density is directly proportional to pressure (P) and molar mass (M), and inversely proportional to temperature (T).
