Exam: GRE (Verbal)

Definition: Describing a substance that has undergone a chemical process called hydrocracking, which breaks down large molecules into smaller ones using hydrogen and heat.

Example: The hydrocracked oil is more efficient for fuel production.

Definition: To break down heavy hydrocarbons into lighter products using hydrogen and heat, typically in the context of refining petroleum.

Example: The oil refinery hydrocracked the heavy crude oil to produce gasoline.

Definition: A facility in chemical engineering where a process called hydrocracking occurs, which breaks down large hydrocarbon molecules into smaller, more useful ones, typically in the production of fuels.

Example: The refinery's hydrocracker is essential for producing high-quality diesel fuel.

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 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.
