Yes, it is possible to construct a thermally isolated system in reality. However, it is extremely difficult to achieve complete isolation from external thermal influences.
No, a thermally isolated system does not need to be completely isolated from all external influences. It is only required to be isolated from thermal influences in order to maintain a constant internal temperature.
A thermally isolated system works by preventing the transfer of heat energy between the system and its surroundings. This can be achieved by using insulating materials or creating a vacuum within the system. It also requires a constant energy source to maintain the internal temperature.
No, a thermally isolated system cannot exist without any energy input. In order to maintain a constant internal temperature, the system requires a constant energy source, such as an external power supply or a chemical reaction.
Some examples of thermally isolated systems include vacuum flasks, refrigerators, and insulated containers used for transporting sensitive materials. These systems are designed to minimize heat transfer and maintain a constant internal temperature.
