AIPMT 2008 Main Mock Test

If uncertainty in position and momentum are equal, then uncertainty in velocity is:

If a gas expands at constant temperature, it indicates that:

The value of equilibrium constant of the reaction $HI(g)\rightleftharpoons \frac{1}{2}{H}_2(g)+\frac{1}{2}{I}_2(g)$ is $8.0$. The equilibrium constant of the reaction $H_2(g)+I_2(g)\rightleftharpoons 2HI(g)$ will be:

If 'a' stands for the edge length of the cubic systems: simple cubic, body centred cubic and face centred cubic, then the ratio of radii of the spheres in these systems will be respectively:

The measurement of the electron position is associated with an uncertainty in momentum, which is equal to $1\times 10^{-18}{\text{g cm s}}^{-1}$. The uncertainty in electron velocity is (mass of an electron is $9\times 10^{-28}\text{g}$):
