Definition: A method used in the oil industry to break down large hydrocarbon molecules into smaller ones, like gasoline or kerosene, by adding hydrogen and using high pressure and a catalyst.

Example: Hydrocracking is an important process in refining crude oil into usable fuels.

Definition: Relating to the movement of liquids and the forces involved when they are in motion.

Example: The hydrodynamic design of the boat allows it to move quickly through the water.

Definition: Relating to the study of fluids in motion and the forces acting on them.

Example: The hydrodynamical properties of the water flow were analyzed in the experiment.

Definition: The area of science that studies how liquids move and behave when they are in motion.

Example: Engineers use hydrodynamics to design efficient ships and submarines.

Definition: Relating to the production of electricity using the energy from flowing water.

Example: The hydroelectric plant provides power to thousands of homes.

Definition: A type of boat that has special wings called hydrofoils, which lift the boat above the water to reduce resistance and allow it to move faster.

Example: The hydrofoil glided smoothly over the waves, making the ride much faster than a regular boat.

Definition: A type of gel that contains a large amount of water and is made from polymers, often used in medical and industrial fields.

Example: The doctor used a hydrogel to help heal the wound more effectively.

Definition: A colorless and flammable gas that is the lightest and most abundant element in the universe, often used in various chemical processes and fuels.

Example: Hydrogen is used in fuel cells to produce electricity.

Definition: A type of enzyme found in some microorganisms that helps in chemical reactions involving hydrogen, either by breaking down substances or by using hydrogen gas.

Example: The hydrogenase enzyme plays a crucial role in the energy metabolism of certain bacteria.

Definition: To combine a substance with hydrogen, often to change its chemical structure, such as turning liquid oils into solid fats.

Example: The process to hydrogenate vegetable oils makes them more stable for cooking.
