Bulk properties refer to the characteristics of materials that are determined by the collective behavior of their large number of atoms or molecules, rather than their individual atomic or molecular properties. These properties, such as density, thermal conductivity, and electrical conductivity, are essential for understanding and predicting the performance of materials in various applications.

Collective behavior refers to the spontaneous and unstructured actions of a group of people, often occurring in situations where traditional norms and institutions are disrupted or unclear. It is a key area of study in sociology, examining phenomena like crowds, social movements, and mass hysteria to understand how individuals act in groups and how these actions can lead to social change.

Density is a measure of how much mass an object or substance has in a given volume, often expressed in units like kilograms per cubic meter or grams per cubic centimeter. It is a fundamental property used to characterize materials and can affect how substances interact, float, or sink in different environments.

Thermal conductivity is a material property that indicates the ability of a material to conduct heat, playing a crucial role in determining how quickly heat can be transferred through a material. It is essential in applications ranging from building insulation to electronic device cooling, influencing energy efficiency and thermal management strategies.

thermal conductivity

Electrical conductivity is a measure of a material's ability to allow the flow of an electric current, which is determined by the availability and mobility of charge carriers such as electrons or ions. It is a critical property in determining the suitability of materials for applications in electronics, energy transmission, and electrochemical processes.
