الصيغة
Density: ρ = m / V. Mass: m = ρ × V. Volume: V = m / ρ. Where ρ is density, m is mass, and V is volume.
الأسئلة الشائعة
What is density?
Density is mass per unit volume (ρ = m/V). It tells you how much matter is packed into a given space.
What are common units for density?
The SI unit is kg/m³. Other common units include g/cm³ (1 g/cm³ = 1000 kg/m³) and g/mL.
How do I find mass from density and volume?
Multiply density by volume: m = ρ × V. For example, 1000 kg/m³ × 0.5 m³ = 500 kg.
Does density depend on temperature?
Yes. Most materials expand when heated, so their density decreases. Water is densest at about 4 °C.
