What is the latent heat of fusion of ice?

• A. 210 kj/kg
• B. 335 kj/kg
• C. 420 kj/kg
• D. 540 kj/kg

Answer: (B)

The latent heat of fusion of ice is the amount of heat energy required to convert ice at its melting point into water without changing its temperature. For ice, this value is approximately 335 kJ/kg. This means that when 1 kilogram of ice is transformed into water at 0 degrees Celsius, it absorbs 335 kJ of energy. This property is crucial in refrigeration processes where phase changes, such as melting and freezing, play a vital role in heat absorption and rejection. Understanding latent heat is essential for determining the efficiency and effectiveness of refrigeration systems in various applications.
