The melting temperature of a certain mass of a solid object is 20°C. When a heat Q is added to the object, its material melts. When an additional amount of Q 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 J g-1 °C-1) for the material.
Let the mass of the solid object be m, and specific latent heat of fusion be L ,
