Read the experiment procedure then fill out the lab report.

Equipment

• Water
• Ice cube tray and freezer
• Ruler or Tape Measure

Procedure

Part I: Measuring Volumes

Measure the volume of a compartment of the ice tray by assuming it has a rectangular shape and using the equation: V = Length x Width x Height.

Fill the ice tray to the top with water and let it freeze overnight.

Measure the volume of the part of the ice cube.

Since the mass of the water does not change when it freezes, the ratio

icewater=(MiceVice)(MwaterVwater)=VwaterVice

Use water = 1000 kg/m3 to determine the mass density of ice, and compare it to the accepted value water = 900 kg/m3. As always, you should use the Relative Difference when comparing values (see earlier lab for the definition of the Relative Difference).

Part II: Determining the Mass Density of Ice

Since the mass of the water does not change when it freezes, the mass of the ice is the same as the mass of the water that you froze. Therefore, Mice = Mwater and the ratio

icewater=(MiceVice)(MwaterVwater)=VwaterVice

Rearranging gives the following equation:

ice=water(VwaterVice)

What to Do:Use water = 1000 kg/m3 and your volume measurements to determine the mass density of ice, and compare it to the accepted value water = 900 kg/m3. As always, you should use the Relative Difference when comparing values (see earlier lab for the definition of the Relative Difference).

Introduction

Lab Format: (Please follow this format for Lab report)

Abstract: A concise description of the experiment that paints a quick picture of the lab and a summary of the results. Do not go into much detail, but provide enough information so that the reader can identify the main points of the lab and the quality of your results.

Introduction: A more thorough description of the experiment that includes any background information that is related to the lab. You should provide enough information so that a reader with the same equipment could reproduce your lab and check your results. Be sure to include any necessary drawings or equations, and be sure to provide any necessary labels on your drawings.

Observations (Measurements): All data should be presented in a clear, easy to follow fashion with units. Tables are especially useful when you have more than one measurement.

Analysis: Include any calculations that were done. All calculations should be clearly presented. All final results must include units.

Results: What were the main results and how well did they agree with any predictions? Were there any major sources of error in you lab that could lead to large uncertainties in your results? Discuss ways to improve your experiment.
