- Your Answer Is Partially Correct An Unknown Material Has A Normal Melting Freezing Point Of 21 6 C And The Liquid Pha 1 (21.88 KiB) Viewed 29 times
Your answer is partially correct. An unknown material has a normal melting/freezing point of -21.6°C, and the liquid phase has a specific heat capacity of 177 J/(kg C"). One-tenth of a kilogram of the solid at -21.6 °C is put into a 0.111-kg aluminum calorimeter cup that contains 0.164 kg of glycerin, The temperature of the cup and the glycerin is initially 25.9°C. All the unknown material melts, and the final temperature at equilibriumis 21.8°C. The calorimeter neither loses energy to nor gains energy from the external environment. What is the latent heat of fusion of the unknown material? Number 11953 Units WER
