Answer:

546 K

Explanation:

V = R*T/P

Since R and P are constant..

T2 = T1 * V2 / V1

V1 = V , V2 = 2V and T1 = 273 K

Putting above values in above equation we get. T2 = 273 *2V/V = 546 K

Answer:

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.
