Question

At what centigrade temperature will a given volume of a gas at $0^{\circ }$C becomes double if pressure remains constant?

• A. ${546}^{\circ }$C
• B. ${200}^{\circ }$C
• C. ${273}^{\circ }$C
• D. ${320}^{\circ }$C

Answer 1

Answer: (C)

${273}^{\circ }$C

$V_1=V;T_1=273+0=273$K

$V_2=2V$

Applying Charle's law as pressure is constant,

$T_2=\frac{2V\times 273}{V}=546$K$={273}^{\circ }$C.

So, the correct option is $C$
