Question

273 ml of a gas at STP was taken to 27°C and 600mm pressure . The final volume of the gas would be

(a) 273 ml (b) 300 ml
(c) 380 ml (d) 586 ml​

Answer 1

The final volume of the gas is 380 ml

Explanation:

We know that,

$\frac{P_1\times V_1}{T_1} = \frac{P_2\times V_2}{T_2}$

The initial condition are,

Pressure , $P_1$= 760 mm

Temperature ,$T_1$ = 273 K

Volume , $V_1$ = 273 ml

The final conditions are,

Pressure , $P_2$ = 600 mm

Temperature, $T_2$ = 273 +27 = 300 k

Volume $V_2$ = ?

$\frac{P_1\times V_1}{T_1} = \frac{P_2\times V_2}{T_2}$

$\frac{760\times 273}{273} = \frac{600\times V_2}{300}$

$V_2$ = 380 ml
