The density of aluminium can be determined through various experimental methods. Here are two methods:
This method involves measuring the buoyant force on a submerged aluminium sample to calculate its density.
Step | Description |
1. Weigh the sample in air | Measure the mass of the aluminium sample. |
2. Submerge in liquid | Submerge the sample in a liquid of known density. |
3. Measure displaced liquid | Calculate the volume of the displaced liquid. |
4. Calculate density | Use the formula: Density = Mass / Volume. |
A method for measuring metal volume:
This technique uses X-ray diffraction to measure the density of crystalline aluminium.
Step | Description |
1. Prepare the sample | Obtain a pure aluminium crystal sample. |
2. X-ray diffraction | Use X-ray diffraction to determine lattice parameters. |
3. Calculate density | Use the lattice parameters to calculate density. |
