Topic: Material Science

A mixture of chemical compounds or elements that have a single chemical composition and solidifies at the lowest temperature than any other composition made up of the same ingredients.

  • A. Phase balanced system
  • B. Eutectic system
  • C. Binary thermally balanced system
  • D. intrinsic system

Answer: B. Eutectic system

Explanation: A eutectic system describes a specific mixture of chemical compounds or elements that has a single distinct chemical composition which solidifies at a lower temperature than any other possible composition of those same ingredients. This particular composition is known as the eutectic composition, and the specific lowest temperature at which it solidifies is called the eutectic temperature.
