0.75kg of air has a pressure of 3bar and a temperature of 125oC , After it has received 900kj of heat at constant volume, find the final temperature and pressureIf the air then expands adiabatically doing 915kj of work,by how much is its internal energy changed during the expansion(b) is the value lower or higher before the heating process

Explain about first law of thermodynamics and application in detail.. like formulas and when it's applicable and much more data. (please don't just give definition...I need everything in detail all concept of entropy...I didn't able to understand)

QUI A piston-cylinder device with a set of stops initially contains 300 g of steam at 1000 Kpa and 400 C. Find the work if the final state IMpa and 250 C, and work if the position of the stops corresponds to 60% of the initial volume and also find the temperature at the final state if P-500Kpa Steam 300 g 1000 Kpy 400°C e

Solve it

Solve it correctly please. I will rate accordingly

Find the work if the final state 1Mpa and 250 C, and work if the position of the stops corresponds to 60% of the initial volume and also find the temperature at the final state if P-500Kpa Steam 300 g 1000 Kpy 400°C e

1. Kittel Ch3-1. Free energy of a two state system. (a) Find an expression for the free energy as a function of 7 of a system with two states, one at energy 0 and one at energy E. (b) From the free energy, find expressions for the energy and entropy of the system. The entropy is plotted in Figure 3.11.

steam at 11 MPa has a specific volume of 0.0196 m^3/kg , find the temperature, the enthalpy, and the internal energy.

If 528 kJ of heat are added to 2.25 kg of helium at constant volume process when the initial temperature is 40 deg. C, find: the change in enthalpy in kJ 869.5 889.5 879.5
