Isothermal heat transfer refers to the process of transferring heat between two objects or systems at a constant temperature, resulting in no change in temperature for either object or system.
Isothermal heat transfer involves heat transfer at a constant temperature, while adiabatic heat transfer involves heat transfer without any exchange of heat with the surroundings. This can result in a change in temperature for the objects or systems involved.
The rate of isothermal heat transfer can be affected by the thermal conductivity of the materials involved, the surface area of the objects, and the temperature difference between the objects or systems.
Isothermal heat transfer is commonly used in refrigeration and air conditioning systems, as well as in chemical reactions where maintaining a constant temperature is important for the reaction to occur.
One limitation of isothermal heat transfer is that it requires a constant temperature, which may not be possible in some real-world situations. Additionally, some heat loss or gain may still occur, resulting in a slight change in temperature.
