The melting point of a substance X is 3.0∘C and its latent heat of fusion is 98kJ⋅kg−1. In liquid form, X has a specific heat capacity of 2500J⋅kg−1⋅K−1 and in solid form, it has a specific heat capacity of 1800J⋅kg−1⋅K−1. How much energy is required to produce 1.0kg of liquid at 25∘C from solid at −12∘C? Give your answer in kJ without a unit.
