Definition: A material or surface that wears away or is removed when exposed to heat, often used in spacecraft or rocket engines to protect against high temperatures.

Example: The spacecraft was equipped with an ablator to protect it from the intense heat during reentry into the Earth's atmosphere.

Definition: Something that can be worn away or scraped off through friction or abrasion.

Example: The abradable material was used in the construction of the aircraft to reduce wear and tear.

Definition: A material or substance that can wear away or smooth surfaces through friction.

Example: The abradant material was used to polish the metal surface.

Definition: A material or substance that is used to wear down or smooth surfaces through friction.

Example: The mechanic used an abradant to smooth the rough edges of the metal.

Definition: To separate or cut off a part from a whole, often referring to the natural process of shedding or falling away.

Example: The plant will abscise its leaves in the fall.

Definition: To cut something off or remove it completely.

Example: The surgeon had to abscise the damaged tissue during the operation.

Definition: The quality or ability of a material to take in or soak up liquids or other substances.

Example: The absorbability of the material is crucial for its effectiveness in various applications.

Definition: A measurement that shows how much light is taken in by a material when light passes through it.

Example: The absorbance of the solution increased as more dye was added.

Definition: A person or thing that takes in or soaks up something, such as a liquid or energy.

Example: The sponge acts as an excellent absorber of water.

Definition: This term refers to the measure of how much radiation is absorbed by a surface compared to the amount of radiation that hits it.

Example: The absorptance of the material determines how much light it can absorb.

Definition: This word describes something that can take in or soak up substances, like a sponge. It can also refer to the ability to handle difficult situations or pressure.

Example: The absorptive properties of the material make it ideal for use in filters.

Definition: This term refers to the ability of a surface to take in radiation, expressed as the ratio of the amount of radiation absorbed to the total amount that hits the surface.

Example: The absorptivity of the material determines how much heat it can absorb from sunlight.
