Assuming an ideal gas, the state equation is

PV = nRT .

At constant pressure P and fixed number of moles n, Volume V grows proportionally to temperature T. (R is a universal constant.)

Thus, volume doubles when temperature doubles. At 0°C, the absolute temperature is T = 273.15 K. The double of that is 546.30 K = +273.15°C.

ANSWER

According to Charles's law, \dfrac{V_1}{V_2}=\dfrac{T_1}{T_2}

V_2=2V_1V

T_1=273 KT

=273K

substituting in the above equation we get,

\dfrac12=\dfrac{273}{T_2}

=546 K

In celsius scale substract 273 from 546 so T_2=273^\circ CT

=273

C

Hence, option (B) is correct.
