Question

Two litres of gas are maintained at 25$^\circ$C and two atmospheric pressure. If the pressure is doubled and absolute temperature is halved, the gas willnow occupy

• A. 2 .0 litres
• B. 4.0 litres
• C. 0.5 litres
• D. 10 litres

Answer 1

Answer: (C)

0.5 litres

Answer 2

$\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}$ $\frac{2 \times 2}{(273 + 5)} = \frac{4 \times V_2}{(273 + 5)/2}$ $V_2$ = 0.5 litre
