Passage - II : Liquids do not have definite shape and size, they are taken in a vessel. Their expansion (or) contraction takes place with respect to the container in which they arc considered. The volume coefficient of expansion relative to the vessel is termed as coefficient of apparent expansion ( gamma_(a) ) and the volume coefficient of expansion of the liquid is termed as absolute ( gamma_(R) "or" gamma_(L ) ). In some of the arrangements mentioned as per the instructions. solve the problems. The height of the liquid column in the cylindrical container is h_0 at 0^(@) C. If the temperature of the liquid raises to 0^(@) C, assuming the coefficient of volume expansion of liquid and solid as gamma_(L ) and gamma_(S) respectively, the height of the liquid in the vessel ( h_( theta )) as a function of temperature ( theta) is |

Answer» `h_( theta ) = h _(0) [ 1+ ( gamma_(L)- gamma_(s) ) theta ]` |
