EXPERIMENT PROBLEM: A certain mechanical device with a mechanism similar to a piston contains a certain amount of gas. Upon compression from 55 L to 15 L, the gas released 350 J of heat. Experiment shows that the external pressure of the mechanical device is given by: Pext = AsinV + BcosV + CsinhV + DcoshV Where: A = 100 B = 80 C = 1x10⁻²⁵ D = 5x10⁻³⁰ sin = sine function cos = cosine function sinh = hyperbolic sine function cosh = hyperbolic cosine function V = in liters Pext = in atm Determine the change in internal energy of the system in kilojoules. TIP: usually, expressions involving trigonometric functions are in radians.

Assume that there is an isolated system which has 2 compartments that are separated by a wall that is adiabatic, impermeable, and movable. The said system contains an ideal gas. One compartment has NO-0.75 gas moles and is initially held at 200K. Then, the other compartment has N2)-0.5 gas moles and is initially held at 300K. Moreover, the initial pressures are P(1)-p(2)-2 atm. Find the final volume of each compartment at equilibrium.
1000 cm^3 of air at an initial pressure of 1.10 × 10^5 Pa and temperature of 300 K undergoes the following changes: heat the air at constant pressureuntil its temperature reaches 390 K and then compress the air isothermallyuntil it returns to the initial volume of 1000 cm3and finally allow the air to cool so that its final pressure is 1.10 × 10^5 Pa. i. Draw a P-V graph to represent the changes undergone by the air ii. Calculate the maximum volume of the air. iii. What is the maximum pressure of the air? iv. State how the net work done on the air for the whole process can bedetermined
Q1. For a compression process with isothermal conditions and PV=Constant , will the moles of compressed material stay constant?? Prove your answer
Fluid mechanics The piston-cylinder unit contains a large amount of 20 atm and 0.04 m² of liquid. The liquid expands reversibly according to the law pv' = Cuntil its volume reaches twice its initial value. The liquid is then cooled again under constant pressure until the piston returns to its starting position. Now heat is applied reversibly while the piston is blocked until the pressure rises to the initial value of 20 atmospheres. Calculate the network formed by the liquid. Assume liquid means fluid
There is 2 kilograms of gas with a molecular weight of 28, located in a rigid tank which is closed and equipped with an electrical resistor. A fixed resistance of 10 amperes and a voltage of 12 volts are applied to this system for 10 minutes. When thermal equilibrium is reached, it is seen that the temperature of the gas rises by 40.3°C. The heat transfer to the environment is estimated at 20 W. Assuming ideal gas behavior, in this temperature range the gas Find the average value of its specific heat Cp. (kj/kg K)
