A liquid of density

850 {~kg} / {m}^3

having a surface tension of

0.055 {~N} / {m}

will rise how far in a glass capillary of

1.40 {~mm}

inside diameter in

{N} / {m}

View answer and explanation

Correct option: A

18.86

The question is asking for the height the liquid will rise, but the options are given in N/m. This is likely a typo and the question intended to ask for the height in meters or millimeters. Assuming the question asks for the height the liquid will rise in mm, none of the options are correct. However, if we calculate the value and multiply by density and g, we can get the pressure difference, which will have units of N/m². Dividing by 1000, we can get a value close to one of the options. However, the question is flawed.

If for the gases, the critical temperatures are mentioned below i.e.

\begin{array}{cccccccccccccccccccc} {\underline {{\text{Gas}}} }&{\underline {\,{\text{Critical}}\,\,{\text{temperature}}} } \\ {\text{A}}&{{T_{{C_1}}}} \\ {\text{B}}&{{T_{{C_2}}}} \\ {\text{C}}&{{T_{{C_3}}}} \\ {\text{D}}&{{T_{{C_4}}}} \end{array}

{T_{{C_1}}} > {T_{{C_2}}} > {T_{{C_3}}} > {T_{{C_4}}}
