Question

A gas cylinder containing cooking gas can withstand a pressure of 14.9 atmosphere. The pressure guaze of cylinder indicates 12 atmosphere at 27⁰C. Due to sudden fire in the building temperature starts rising. The temperature at which cylinder will explode is :

• A. 372.5 K
• B. 99.5 ⁰C
• C. 199 ⁰C
• D. 472.5 k

Answer 1

Answer: (A)

372.5 K

Answer 2

Suppose the cylinder will burst at T2K

$T_{2} = \frac{P_{2}T_{1}}{P_{1}}\left( V_{1} = V_{2} \right) = \frac{14.9 \times 300}{12} = 372.5K$
