A container contains three liquds as shown in the figure. The specific gravity of liquid 1 and liquid 2 are 0.8 and 1.2 respectively. A small hole having area 10^(-6) m^(2) at point P is as shown in the figure. Initially hole is closed. The cross-sectional area of container is 50 cm^(2) . assume all liquids ae ideal and neglect any type of friction between liquid and container.

The temperature of a hot liquid in a container of negligible heat capacity falls at the rate of 3K//min due to heat emission to the surroundings, just before it begins to solidify. The temperature then remains constant for 30min , by the time the liquid has all solidfied. Find the ratio of specific heat capacity of liquid to specific latent heat of fusion.
