Question

Equation of gas in terms of pressure (P), absolute temperature (T) and density (4) is

• A. $\frac{P_{1}}{T_{1}d_{1}} = \frac{P_{2}}{T_{2}d_{2}}$
• B. $\frac{P_{1}T_{1}}{d_{1}} = \frac{P_{2}T_{2}}{d_{2}}$
• C. $\frac{P_{1}d_{2}}{T_{1}} = \frac{P_{2}d_{1}}{T_{1}}$
• D. $\frac{P_{1}d_{1}}{T_{1}} = \frac{P_{2}d_{2}}{T_{2}}$

Answer 1

Answer: (A)

$\frac{P_{1}}{T_{1}d_{1}} = \frac{P_{2}}{T_{2}d_{2}}$

Answer 2

$PV = \mu RT = \frac{m}{M}RT$ Ž $P = \frac{d}{M}RT$ (Density$d = \frac{m}{V}$)

Ž $\frac{P}{dT} =$constant or $\frac{P_{1}}{d_{1}T_{1}} = \frac{P_{2}}{d_{2}T_{2}}$
