Question

experimental investigation to show the latent heat of fusion of ice ❄

Answer 1

Answer:

We first need to obtain some ice. Sit the ice in a bowl at room temperature till than it is starting to melt. Then In a freezer, ice is kept at a temperature well below freezing.  We need to allow the ice to sit outside the freezer long enough that is warms up to freezing .  The ice can't get warmer than freezing; once it reaches freezing it will start to melt.

Add 200 to 250 mL of warm tap water (40o C  or less so that there isn't too big of a temperature difference between the water and air) to the styrofoam cup. .  Measure and record the temperature of the warm water just before you are ready to add some ice.  Add one or two ice cubes (or about 1/4 cup of crushed ice) to the warm water and stir gently with the thermometer until the ice is completely melted.  Try to be sure you just add ice and none of the water in the bowl from the melted ice.   You will need to use less ice or more water or both.  Use the graduated cylinder to measure the new volume of the water in the styrofoam cup.  This new volume will be larger than the initial volume because it contains the water from the melted ice.  The difference in the starting and ending water volumes is the mass of the ice that was melted.  Do repeat the experiment once or more time by using a different amount of water, a different amount of ice, and perhaps a different initial water temperature.
