The net heat transfer during the process can be determined using the First Law of Thermodynamics. The work done on the system can be calculated using the formula for work done in a polytropic process. To calculate the percentage increase or decrease in the heat transfer if water replaces the helium, you would need additional information.
The net heat transfer during the process can be determined using the First Law of Thermodynamics. The First Law states that the net heat transfer, Q, is equal to the change in internal energy, ΔU, plus the work done on or by the system, W: Q = ΔU + W.
Since the process is adiabatic and reversible, there is no heat transfer, so Q = 0. The work done on the system can be calculated using the formula for work done in a polytropic process: W = (P₂V₂ - P₁V₁) / (n - 1), where P₁, V₁, P₂, and V₂ are the initial and final pressure and volume, respectively, and n is the polytropic index.
To calculate the percentage increase or decrease in the heat transfer if water replaces the helium, you would need to know the specific heat capacity of water and the change in temperature of the system.
