What are the densities of Al, Ge and Si ?
What are the densities of Al, Ge and Si ?
Solution and Explanation
Al = 2.7 g/cm3, Ge = 5.323 g/cm3, Si = 2.33 g/cm3.
The densities of aluminum (Al), germanium (Ge), and silicon (Si) are as follows:
Aluminum (Al): The density of aluminum is approximately 2.70 grams per cubic centimeter (g/cm³).
Germanium (Ge): The density of germanium is around 5.32 grams per cubic centimeter (g/cm³).
Silicon (Si): The density of silicon is about 2.33 grams per cubic centimeter (g/cm³).
Please note that these values are approximate and can vary based on factors such as temperature and pressure.

Solid State
Solids are substances that are featured by a definite shape, volume, and high density. In the solid-state, the composed particles are arranged in several manners. Solid-state, in simple terms, means "no moving parts." Thus solid-state electronic devices are the ones inclusive of solid components that don’t change their position. Solid is a state of matter where the composed particles are arranged close to each other. The composed particles can be either atoms, molecules, or ions.
Types of Solids:
Based on the nature of the order that is present in the arrangement of their constituent particles solids can be divided into two types;
- Amorphous solids behave the same as super cool liquids due to the arrangement of constituent particles in short-range order. They are isotropic and have a broad melting point (range is about greater than 5°C).
- Crystalline solids have a fixed shape and the constituent particles are arranged in a long-range order.
