IB PHYSICS > PRACTICAL WORK > IB IA EXPERIMENTS [|IA criteria checklist.doc] - always a good idea to look at this before submitting your work. =PRACTICAL: MEASUREMENT OF SPECIFIC LATENT HEAT OF FUSION OF ICE=

APPARATUS:
Calorimeter, thermometer, weighing scales, stirring rod

PROCEDURE:
Add small pieces of ice to about 150ml of warm water (about 10 degrees above room temperature) until it cools to about 10 degrees below RT. //By having the temperature change be either side of RT, we try to balance heat loss/gain to the surroundings.// Measure and not the masses of the melted ice, water and calorimeter//;// the starting and finishing temperatures.
 * Using an insulated calorimeter, melt small pieces of ice in water and calculate the specific latent heat of fusion.**

Heat gained to melt ice = Heat lost to cool water - Heat gain to warm melted ice Q = mc(∆T) Mass of water Mass of ice Initial temp of water Final temp of water
 * CALCULATION**
 * Sample Measurements:**
 * Mass of calorimeter**

Calculate the heat gained by the ice **per gram of ice**

ASSESSMENT:
Calculate the specific latent heat of fusion of ice with uncertainties. Write up the data, conclusion and evaluation.
