At what temperature, the volume of 'V' of a certain mass of a gas at 3

Question

At what temperature, the volume of 'V' of a certain mass of a gas at

37^{o} C

will be doubled, keeping the pressure constant?

Options:

A . 327o C

B . 347o C

C . 527o C

D . 54o C

Answer: Option B
:
B

\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}

V_{1} = V, T_{1} = 37 + 273 = 310 k

V_{2} = 2 V, T_{2} = ?

\frac{V}{310} = \frac{2 V}{T_{2}}

T_{2} = 620 K = 347^{o} C
