Question

According to the ideal gas law, PV is equal to

• A. $nRT$
• B. $\frac{RT}{n}$
• C. $\frac{nT}{R}$

Answer 1

The correct option is A $nRT$

$\bullet$ According to Boyle's law, V $\alpha$ 1/P

$\bullet$ According to Charles' law, V∝ T

$\bullet$ According to Avogadro’s law, V $\alpha$ n

$\bullet$ Combining the three laws we get the ideal gas law i.e.

V $\alpha$ nT / P
or
PV = nRT

Where,
$P$ = Pressure
$V$ = Volume
$n$ = Number of moles of an ideal gas
$R$ = Gas constant
$T$ = Temperature
