Definition: A mixture of two or more liquids that has a constant boiling point and composition, meaning it behaves the same way when it turns into vapor as it does in liquid form.

Example: The azeotrope of ethanol and water cannot be separated by simple distillation.

Definition: A type of chemical compound that includes a specific group of three nitrogen atoms (N3) bonded together.

Example: Sodium azide is commonly used in laboratories as a preservative and in airbags.

Definition: Relating to or containing a specific chemical group made up of nitrogen atoms.

Example: The azido compound is used in various chemical reactions.

Definition: A chemical group consisting of three nitrogen atoms bonded together, often used in organic chemistry and related to azide compounds.

Example: The azido group is commonly used in various chemical reactions to introduce nitrogen into organic molecules.

Definition: The angle measured horizontally from a reference direction, usually north, to a point where a vertical line through an object meets the horizon, often used in navigation and astronomy.

Example: The navigator used a compass to determine the azimuth of the distant island.

Definition: Relating to a type of map projection that keeps the direction from a specific point accurate, or concerning angles measured in a horizontal circle.

Example: The azimuthal projection is often used in navigation to represent the shortest path between two points.

Definition: In a way that relates to the angle measured from a reference direction, usually in a horizontal plane.

Example: The satellite moved azimuthally to capture images of the Earth's surface.

Definition: A type of organic compound that has a five-sided ring structure, which includes at least one nitrogen atom and may contain double bonds.

Example: Azoles are commonly used in agriculture as fungicides.

Definition: Relating to soils that do not have distinct layers or zones, often resembling the original material they come from.

Example: The azonal soils in the region are important for understanding the geological history.

Definition: Relating to a medical condition characterized by an excess of nitrogenous waste products in the blood.

Example: The doctor explained that the patient's azotemic condition required immediate treatment.

Definition: To treat or combine with nitrogen, often in a chemical process.

Example: The scientists decided to azotize the soil to improve its fertility.
