Q. On $0℃$ pressure measured by barometer is $760\ mm.$ What will be pressure at $100℃$
A) $760\ mm$
B) $730\ mm$
C) $780\ mm$
D) None of these
Explanation
(d) $P \propto T \Rightarrow \frac{P_{2}}{P_{1}} = \frac{T_{2}}{T_{1}} = \frac{(273 + 100)}{(273 + 0)} = \frac{373}{273}$
$\Rightarrow P_{2} = \frac{760 \times 373}{273} = 1038mm$
