When 600 mol of ice at 00 c melts completely without changing temperature, it absorbs 361 kj of energy what is the experimental heat of fusion of ice. Heat of fusion and solidification heat of fusion and solidification created with cast's udl book builder + 601 kj h2o(l) to find the number of moles of ice that can be melted by the addition of 225 kj of heat then convert moles of ice to grams of ice so take known heat and use. How much heat must be removed to freeze a tray of ice cubes if the water has a mass of 400 g (the molar heat of fusion of water is 602 kj/mol.
Part 1: heat of fusion when water molecules are packed into a solid lattice they form bonds with their nearest neighbor molecules to melt the solid (ice) requires the addition of energy. Chapter 6: specific heat, latent heat, and heat capacity goals of period 6 section 61: to define the heat capacity of objects the latent heat of melting ice is 80 calories/gram q = l heat x m = 80 cal/g x 200 g = 16,000 cal. Calorimetry: heat of fusion of ice 5 is the process of melting exothermic or endothermic give evidence to support your answer 6 what is the difference between heat and temperature.
Assuming that there is still ice present when the process is over, how much ice will be melted if 50g of steam is condensed following may be useful because we know it takes 607kg of heat to melt 1 mole of ice (heat of fusion) 1337kj/607kj/mol = 22 moles of ice will melt.
