A liquid at $$30^\circ C$$ is poured very slowly into a Calorimeter that is at temperature of $$110^\circ C$$ . The boiling temperature of the liquid is $$80^\circ C$$ . It is found that the first 5 gm of the liquid completely evaporates. After pouring another 80 gm of the liquid the equilibrium temperature is found to be $$50^\circ C$$ . The ratio of the Latent heat of the liquid to its specific heat will be $$^\circ C$$
