Question

If ice cubes are taken from a freezer and used immediately will the value of latent heat of fusion be less or greater than the theoretical value

Answer 1

Answer:

Object of the Experiment

Energy is required to change water from a solid to a liquid, i.e. to melt ice. In this experiment you will try to measure the latent heat of fusion of ice (LHice), the energy needed (per gram) to melt ice. The needed energy will come from a cup of warm water. The amount of water and its temperature will be measured before adding some ice and then again after the ice has been melted. These data will be used in an energy balance equation to determine LHice.
