Once the liquid has solidified the system is in thermal, Ask an Expert

Academics

Assume 2,000kJ of heat energy is removed from a liquid-based system (25.0 kg of liquid with a specific heat of4.75 J/g/C). At the end of a 10 C cooling process all of liquid has just changed to a solid. Once the liquid has solidified, the system is in thermal equilibrium (no temperature change in the solid). What is the latent heat of fusion (kJ/kg) of the unknown liquid?
