An isolated thermodynamic system is a system that does not exchange matter or energy with its surroundings. In other words, it is a closed system with no mass or energy transfer across its boundaries.
a) No heat is transferred:
In an isolated system, there is no heat transfer because there is no interaction with the surroundings. Heat transfer occurs when there is a temperature difference between the system and its surroundings, allowing for the flow of thermal energy. However, in an isolated system, this interaction is absent, so no heat is transferred.
b) No work is done:
Similarly, in an isolated system, no work is done because work is defined as the transfer of energy due to a force exerted over a distance. In order for work to be done, there must be an external force acting on the system or vice versa. In an isolated system, there are no external forces or interactions with the surroundings, so no work is performed.
c) No mass flows across the boundary of the system:
As mentioned earlier, an isolated system does not exchange matter with its surroundings. This means there is no mass flow across the boundaries of the system. Mass transfer can occur through various means such as diffusion or convection, but in an isolated system, these processes are not allowed.
d) No chemical reaction takes place within the system:
Chemical reactions involve the rearrangement of atoms or molecules to form new substances. In an isolated system, there are no external influences or interactions, so no chemical reactions can take place. Chemical reactions often require the presence of reactants and catalysts, which are typically obtained from the surroundings. However, in an isolated system, these reactants or catalysts are not available.
Overall, an isolated thermodynamic system is characterized by the absence of heat transfer, work done, mass flow, and chemical reactions. It is a closed system that does not interact with its surroundings in any way.
