Definition: Describing a condition where the pressure is the same or equal in different areas or systems.

Example: The isopiestic process ensures that the pressure remains constant throughout the experiment.

Definition: Not a valid English word.

Example: Not available.

Definition: A line on a map or graph that connects points with the same value of a certain measurement, like temperature or pressure.

Example: The meteorologist used an isopleth to show areas of equal rainfall on the weather map.

Definition: A clear, colorless liquid that is used mainly to produce synthetic rubber and is known for being flammable and volatile.

Example: Isoprene is a key ingredient in the production of synthetic rubber used in tires.

Definition: Relating to a type of organic compound that has a specific structure based on isoprene units, often found in natural substances like rubber and certain vitamins.

Example: The isoprenoid compounds in the plant contribute to its aroma and flavor.

Definition: A type of chemical compound that is made from one or more units of isoprene, which is a building block for many natural substances.

Example: Many essential oils contain isoprenoids that contribute to their fragrance and therapeutic properties.

Definition: Describing something that has the same density as another substance or mixture.

Example: The isopycnic method is often used in laboratories to separate different components based on their densities.

Definition: A line that connects points on a chart where the density is the same.

Example: The isopycnic line on the graph shows where the density remains constant across different areas.

Definition: Describing a condition where two solutions have the same osmotic pressure, meaning there is no net movement of water between them.

Example: The two solutions were isosmotic, so there was no change in the cell's volume.

Definition: A property in quantum physics that describes the behavior of certain subatomic particles, indicating how they can exist in different charge states, similar to how spin describes their angular momentum.

Example: In particle physics, isospin helps to explain the similarities between protons and neutrons.

Definition: A condition in which the Earth's crust is balanced and supported by the flow of rock material beneath it, ensuring that different areas of the crust maintain equal pressure and elevation.

Example: The concept of isostasy helps explain how mountain ranges can exist without sinking into the Earth.

Definition: Relating to the balance of the Earth's crust and the forces acting on it, particularly in terms of weight and buoyancy.

Example: The concept of isostatic adjustment explains how the Earth's crust responds to changes in weight, such as the melting of glaciers.

Definition: A condition where two opposing forces are balanced, often used in the context of geological or physical processes.

Example: The isostatic adjustment of the Earth's crust occurs when weight is removed from the surface.

Definition: In a way that relates to isostasy, which is the equilibrium of the Earth's crust floating on the denser, underlying mantle.

Example: The geological features were formed isostatically, showing the balance of forces in the Earth's crust.
