Isolated systems

[FrankieClarke2C]

In an isolated system, are we assuming that it is constant volume?

[Dimitri Speron 1C]

An isolated system does not necessarily have constant volume, but it could. Isolated just means that there is no exchange of heat or matter with the surroundings.

[Patrick Cai 1L]

If needed, say there is a gaseous phase reactant or product in the system, the question would typically make a note to say either pressure or temperature is constant.

[Amy Dinh 1A]

An isolated system is a system that has no contact with its surroundings, but it may or may not have a fixed volume, depending on its conditions.

[Philipp_V_Dis1K]

An isolated system's internal energy stays constant or increases, so it's unlikely for it to have a changing volume

[Megan_Ervin_1F]

A good example of an isolated system would be a bomb calorimeter no energy is exchanged with the surroundings

[Miya Lopez 1I]

How could the volume change in an isolated system? Would the system just expand on its own?

[Zubair Ahmed 1L]

An isolated system juts implies that that there is no exchange of energy or matter with the surroundings. An isolated system could have a constant volume but it is not necessary.

[Esther Lee 4H]

I think it just means that there is little to no chance of the system being affected by the surroundings

[Cynthia Aragon 1B]

An isolated system refers to a system that does not exchange matter, heat, or work with the surroundings. Thus, what remains constant as time progresses is the mass and total energy of the system.

[shaunajava2e]

An isolated system is a thermodynamic system that cannot exchange either energy or matter outside the boundaries of the system. An isolated system differs from a closed system by the transfer of energy. Closed systems are only closed to matter, energy can be exchanged across the system's boundaries.
