Understanding Density
Density is a key physical property defined as mass per unit volume (density = mass/volume). Different substances have varying densities, which can help us compare them. Here’s a breakdown of the substances in question, arranged in order of increasing density.

Order of Increasing Density
1. **Air**
- Density: Approximately 1.2 kg/m³
- Lightest among the substances listed.
2. **Exhaust from the Chimneys**
- Density: Varies, but generally around 1.2 to 1.5 kg/m³ in gas form.
- Slightly denser than air due to water vapor and particulate matter.
3. **Cotton**
- Density: About 0.5 to 1.5 kg/m³ when in loose form.
- Typically lighter than water but varies with compression.
4. **Water**
- Density: 1,000 kg/m³ at 4°C.
- A common reference point for density comparisons.
5. **Honey**
- Density: Approximately 1,400 kg/m³.
- Heavier than water due to its sugar content.
6. **Chalk**
- Density: Roughly 2,700 kg/m³.
- A solid substance weighing significantly more than water.
7. **Iron**
- Density: About 7,870 kg/m³.
- The densest material on our list, making it very heavy compared to others.

Conclusion
In summary, the arranged order from lowest to highest density is: **Air < exhaust="" from="" the="" chimneys="" />< cotton="" />< water="" />< honey="" />< chalk="" />< iron**.="" understanding="" these="" differences="" is="" crucial="" in="" various="" scientific="" applications,="" including="" buoyancy="" and="" material="" selection.="" iron**.="" understanding="" these="" differences="" is="" crucial="" in="" various="" scientific="" applications,="" including="" buoyancy="" and="" material="" />
