Definition: The area of science that studies how liquids behave when they are not moving and how they respond to pressure.

Example: Hydrostatics is important for understanding how ships float and how pressure changes with depth in water.

Definition: Relating to hot water, especially in geological contexts where hot water is associated with volcanic activity or mineral deposits.

Example: The hydrothermal vents in the ocean floor support unique ecosystems.

Definition: In a manner that relates to or involves hot water, especially in geological processes.

Example: The minerals were deposited hydrothermally, creating unique formations in the cave.

Definition: Relating to or exhibiting a response to water, especially in the growth or movement of plants towards moisture.

Example: The hydrotropic response of the roots helps the plant find water in dry soil.

Definition: Having water as part of its structure or composition, often in a chemical form.

Example: The mineral is classified as hydrous because it contains water molecules in its crystal structure.

Definition: A type of chemical compound that includes a hydroxyl group, which is made up of one oxygen atom and one hydrogen atom.

Example: Sodium hydroxide is commonly used in cleaning products.

Definition: Relating to or containing a hydroxyl group, which is a chemical group made up of one oxygen atom and one hydrogen atom.

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

Definition: A mineral that is a major component of bone, made of calcium and phosphate, which helps give bones their strength.

Example: Hydroxyapatite is essential for maintaining the structure and strength of bones in vertebrates.

Definition: A chemical group made up of one oxygen atom and one hydrogen atom, often found in various compounds like acids and alcohols.

Example: The hydroxyl group is essential in the structure of alcohols.

Definition: A colorless crystalline compound used in chemical reactions, particularly as a reducing agent in organic synthesis.

Example: Hydroxylamine is often used in laboratories for various chemical reactions.
