The sink-float method is often used to identify the type of glass material found at crime scenes by determining its density. Several different types of glass of known density are placed into solutions of varying densities. Determine whether each glasspiece will sink, float, or do neither when immersed in the given solution.

Explanation:

The density of an object is a ratio of the mass (or quantity of matter in the object) to its volume.

Mathematically, density = mass/ volume.

The more dense an object, the higher will be its dense. Density can be thought of as a comparison of how heavy objects having the same are. Objects with a higher density, are heavier than objects with a lower density. For example, between equal volumes of air and water, water is heavier.

The density of solid object will determine whether it will float, sink or neither float nor sink in a given liquid. The conditions for floating of objects in a liquid is given as follows:

Density of solid > Density of liquid : solid will sink

Density of solid = Density of liquid : solid will neither sink nor float

Density of solid < Density of liquid : solid will float

Using the above criteria to analyze the given glass materials in their respective liquids:

Glass that will sink: alkali zinc borosilicate with a density of2.57 g/mL in a solution with a density of 2.46 g/mL; potash soda lead with a density of 3.05 g/mL in a solution with a density of 1.65 g/mL

Glass that will float: soda borosilicate with a density of 2.27 g/mL in a solution with a density of 2.62 g/mL; alkali strontium with a density of 2.26 g/mL in a solution with a density of 2.34 g/mL

Glass that will not sink or float: potash borosilicate with a density of2.16 g/mL in a solution with a density of 2.16 g/mL
