Question

At constant volume the ratio of increase in pressure of an ideal gas per degree rise in kelvin temperature to its original pressure

• A. $\sqrt{3}$
• B. $\frac{1}{273}$
• C. $\sqrt{273}$
• D. $\frac{1}{\sqrt{3}}$

Answer 1

The correct option is B $\frac{1}{273}$

$ PV = nRT
\\ P \propto T
\\ \dfrac {P_1}{P_2} = \dfrac {T_1}{T_2}
\\ T_1 = 273 K
\\ T_2 = 273 + i K
\\ T_2 = 273+(1-273) K
\\ T_2 = 1 K
\\ \dfrac {T_1}{T_2} = \dfrac {1} {273} $

Hence, Option "B" is the correct answer.
