Density

• Density $\left(p\right)\ =$$\ \frac{Mass\ \left(m\right)}{Volume\ \left(V\right)}$
• Density of a liquid: Place measuring cylinder on balance. Add liquid. Reading on measuring cylinder = V, change in mass on balance = m. Use formula.
• Finding the volume of a solid: To find out volume of a regular object, use mathematical formula. To find out volume of an irregular object, put object into a measuring cylinder with water and the rise of water is the volume of the object.
• To find the mass of a solid, use a balance.
• To calculate the density (p) of anything, use the formula: $p\ =$$\ \frac{m}{V}$
• An object will float in a fluid if it’s density is lesser than the density of the liquid, i.e. The volume of fluid displaced has a greater mass than the object itself.
