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 type of medication that mimics the effects of adrenaline and is used to treat slow heart rates.

Example: The doctor prescribed isoprenaline to help increase the patient's heart rate.

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: 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.
