Expert writing Tips
Best practice
When describing materials or substances, specify the context in which they are "different in density". For example, specify temperature and pressure.
Common error
Ensure you specify the units of density (e.g., kg/m³) when using the phrase "different in density" to avoid ambiguity. Without units, the comparison is incomplete.
