Determination of the density of solid bodies

Principle

In the previous experiments on determination of mass and volume (ME 1.3 and ME 1.4), the students have learned that both metal columns have the same volume but different masses. They know that the two objects consist of iron and aluminium. Obviously, the two materials differ in one property. In terms of physics, this property is called density; it is defined as the quotient of mass and volume:

ρ = m/V  in g/cm³

The students are to determine the mass of four solid objects by weighing them. The volumes of the regularly shaped objects are to be established by measuring them with the vernier calliper and then calculating, using V = l  × w  × h ; the volume of the mass piece by using the immersion method.

Benefits

• Real stand material for an esecially stable and safe setup
• Student-suitable experiment descriptions with reports available
