The melting temperature of a certain mass of a solid object is 20°C. When a heat Q is added to the object, its 34 of the material melts. When an additional Q amount of heat is added the material transforms to its liquid state at 50°C. Find the ratio of specific latent heat of fusion (in J/g) to the specific heat capacity of the liquid  (in Jg−1∘C−1 ) for the material.
