Definition: A container used to pour liquid metal into a mold, designed to prevent splashing and often featuring holes at the bottom.

Example: The workers carefully used the tundish to transfer the molten metal into the casting mold.

Definition: A type of chemical compound that is a salt derived from tungstic acid, often used in various industrial applications.

Example: The laboratory tested the properties of tungstate to determine its effectiveness in the reaction.

Definition: A strong and heavy metal that is gray to white in color, known for its high melting point and resistance to corrosion. It is used in various applications, including light bulb filaments and strong alloys.

Example: The light bulb uses a tungsten filament to produce bright light.

Definition: Relating to or containing tungsten, particularly in a specific oxidation state.

Example: The scientist studied the tungstic compounds for their unique properties.

Definition: A layer or membrane that surrounds or encloses an organ or part of the body.

Example: The tunica is essential for protecting the internal structures of the organ.

Definition: Relating to a type of marine animal that has a protective outer covering, or tunic, often found in the ocean.

Example: The tunicate species can be found attached to rocks and other surfaces underwater.

Definition: A type of marine animal that belongs to a group called chordates, which have a tough outer covering and include creatures like sea squirts and salps.

Example: The tunicate is often found attached to rocks in shallow waters.

Definition: The term refers to the measurement of the weight or capacity of a ship, often expressed in tons.

Example: The ship's tunnage was calculated to ensure it could carry the required cargo safely.

Definition: The process in which a particle moves through a barrier that it normally shouldn't be able to pass, often discussed in the context of quantum mechanics.

Example: Tunneling is a fascinating phenomenon that allows particles to pass through barriers in ways that classical physics cannot explain.

Definition: Having a shape or appearance similar to that of a tunnel.

Example: The path through the trees was tunnellike, creating a dark and enclosed feeling.

Definition: Relating to a class of flatworms known as Turbellaria, which are mostly free-living and found in aquatic environments.

Example: The turbellarian species can be found in both freshwater and marine habitats.

Definition: A type of flatworm that lives in water and is not parasitic, often found in freshwater environments.

Example: The turbellarian can regenerate its body parts, making it a fascinating subject for biological studies.
