2. What is Density? Density is mass per volume ratio. The equation to calculate density is = . Density quantify how much matter is packed in a specific amount of space. Mathematically, Density is calculated by dividing the mass of an object over it’s volume. Units of Density are: kg/m , g/cm³, and lb /ft³.  

3. It’s importance in various fields: It helps us understand the behavior of materials under different conditions, like temperature and pressure. And this is essential in many fields to choose certain materials according to their nature, such as engineering fields, food and nutrition, and medical fields. And understanding how materials react to certain weather conditions, helps us understand climate changes. When changes in temperature or pressure happens, it can affect ocean water, in which if it gets warmer, it will expand and take more space.

4. Calculating Density: To calculate density we have to know the mass and volume of that object, then we will divide the mass of that object over its volume. For example, if we have 65kg mass of an object and 10m, it’s density will be 6.5 kilogram per cubic meter. And Finally, the measurement of density should be very accurate.

5. Examples of Density comparison: Water vs Oil: As you know when you put Oil in Water, the Oil floats over the Water, and the reason for that is because the Oil’s density is lower than the Water, meaning it doesn’t have have as much matter packed into it’s space as much as the Water. Wood vs Metal: Metals like Iron is denser than Wood, and that is exactly why Wood will float on top of water, while Metals sinks in Water.

6. Examples of Density comparison: Same Mass

7. Examples of Density comparison: Same Volume

8. Conclusion: In conclusion, density is a fundamental concept that measures how much mass is packed into a specific volume. It plays a vital role in understanding the behavior of materials under different conditions and has wide-ranging implications across numerous fields.
