Definition: A type of medication that acts as a bronchodilator, helping to open up the airways in the lungs.

Example: The doctor prescribed isoproterenol to help the patient breathe easier during an asthma attack.

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 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: A line on a map that connects places with the same temperature at a specific time or over a certain period.

Example: The meteorologist used an isotherm to show the temperature distribution across the region.

Definition: Relating to processes or conditions where the temperature remains constant throughout.

Example: The isothermal process allowed the gas to expand without changing its temperature.

Definition: A line on a map or chart that connects points of equal temperature at a given time.

Example: The meteorologist used an isothermal map to show the temperature distribution across the region.

Definition: In a way that maintains a constant temperature during a process or reaction.

Example: The gas expanded isothermally, keeping the temperature steady throughout the experiment.

Definition: A type of chemical compound that includes a specific group of atoms known as the isothiocyanate group, which is related to isothiocyanic acid.

Example: Isothiocyanates are found in various plants and are known for their potential health benefits.

Definition: Describing a solution that has the same concentration of dissolved substances as another solution, especially in relation to blood, which helps maintain balance in cells.

Example: The doctor recommended an isotonic solution for the patient to help with hydration.

Definition: In a way that maintains equal pressure or concentration, often used in scientific contexts.

Example: The solution was mixed isotonically to ensure proper balance in the experiment.

Definition: The condition in which two solutions have the same concentration of solutes, resulting in no net movement of water across a semipermeable membrane.

Example: The isotonicity of the saline solution is important for patient safety during intravenous therapy.
