2. Density Topic/QuestionFacts What is Density? What are the units for density? -Amount of matter packed into a certain amount of space -D = m = mass V Volume -g/cm 3 -kg/m 3 -g/ml -kg/L

3. Density Topic/QuestionFacts What is the density of gold? How would the density of gold change if a block of it was cut in half? 19.3 g/cm 3 - It would not change - All solids of the same material have same density

4. Density Topic/QuestionFacts For most solids, does the density ever change (if at the same temperature)? -No -Every element has its own unique density based on its molecular structure.

5. Density Topic/QuestionFacts Assume you have a loaf of bread. Then you smash it in half. What happens to the: 1.Mass 2.Volume 3.density Mass - would not change Volume - would decrease Density - would increase

6. Closing What is density and how can it be measured? Be specific!
