What is Isothermal?
A process occurring at constant temperature. For an ideal gas, isothermal expansion follows Boyle's law (PV = constant). In thermodynamics, isothermal processes involve heat exchange with the surroundings to maintain constant temperature.

Frequently Asked Questions
A process occurring at constant temperature. For an ideal gas, isothermal expansion follows Boyle's law (PV = constant). In thermodynamics, isothermal processes involve heat exchange with the surroundings to maintain constant temperature.
Isothermal conditions are used in: isothermal titration calorimetry (ITC, measures binding thermodynamics), isothermal compressibility measurements, isothermal phase diagram determination, and in thermodynamic analysis where temperature control eliminates heat as a variable.
Maintaining isothermal conditions in highly exothermic reactions requires adequate cooling capacity. If cooling fails, temperature rises (adiabatic conditions), potentially leading to thermal runaway. Heat exchangers and cooling systems in isothermal industrial reactors are critical safety systems.
The formula or notation for Isothermal is: T = constant; PV = k
