The object with multiple layers or air separated by air is called an insulator. Examples of insulators include rubber, plastic, and air-filled gaps in windows.
An insulator is a material designed to impede the transfer or conduction of heat, electricity, or sound. These materials typically consist of multiple layers or air gaps, creating a barrier that inhibits the flow of energy. Among the various insulators, rubber and plastic stand out as common examples due to their poor thermal and electrical conductivity.
These materials find widespread use in electrical insulation, where preventing the flow of electricity is crucial for safety and proper functioning of electronic devices. Additionally, air-filled gaps, such as those found in double-pane windows, act as effective thermal insulators, reducing heat transfer between the interior and exterior environments.
The insulating properties of these materials and structures make them indispensable in diverse applications, from electrical engineering to construction, contributing to enhanced energy efficiency and safety.
