If xn = k then ln(xn) = ln(k)AMtsukuba said:I was thinking I would have to use log to figure out n maybe?
tsukuba said:I came to this but now I am not sure how to isolate for n
ln(130) n*ln(0.07) = ln(100) n*ln90.08637)
Boundary work in thermodynamics refers to the work done by a system as it expands or compresses against a constant external pressure. It is a form of mechanical work that occurs at the boundary between the system and its surroundings.
Boundary work is calculated by multiplying the external pressure by the change in volume of the system. This can be represented by the equation W = PΔV, where W is the boundary work, P is the external pressure, and ΔV is the change in volume.
Boundary work is a specific type of mechanical work that occurs at the boundary of a system, while other forms of work, such as shaft work or flow work, occur within the system. Boundary work is also dependent on the external pressure, while other forms of work may not be affected by external factors.
Boundary work is an important concept in thermodynamics as it allows us to understand the energy exchange that occurs between a system and its surroundings. It is also a key factor in determining the efficiency of processes and the maximum possible work that can be obtained from a system.
Yes, boundary work can be negative if the system is compressed by an external pressure. This means that work is being done on the system, and energy is being transferred from the surroundings to the system. In contrast, positive boundary work occurs when the system expands and does work on the surroundings.
