Assuming that the gas in these processes is an ideal one, is the change in internal energy in an isochoric process (volume remaining constant) the same as the change in internal energy of isobaric process (pressure remaining constant)? Mathematically I can derive that they're equivalent, but ...
During an adiabatic expansion of 2 moles of a gas the chang in internal energy was found to be equal to -100 J. The work done during the process will be equal to Azero B−100 joule C200 joule D100 jouleSubmit An ideal gas system undergoes an isothermal process, then the work done ...
aHowever, such theoretical process is not easy to realize in practice. As for an isothermalexpansion, a heat source is needed for energy input into the system because the internal energy of gas remains constant during isothermal expansion. Obviously, there exists no such heat source in the ...
In a typical gravitational wave detector, the two vibrating cavities in the trajectories are at a ninety-degree angle with respect to each other, like in the Fabry-Perot-Michelson interferometer (FPMI). In the first phase of the ETpathfinder’s investigation, trajectories contain an FPMI. Then...
In this process, the pump must supply the fluids with enough energy to compensate for pressure losses caused by friction and gravity, with the aim of reaching a large flow rate at reasonable economical costs. In fact, artificial lift methods play a key role in maintaining the oil production ...
Tang (Tang et al., 2004) has developed an inorganic gel system using silicate and cross-linker (high salinity formation water) to form an inorganic gel coating profile control system. The system coats on the core framework well. It has excellent temperature resistance, salt resistance, and ...

Understanding the physics at extreme thermodynamic points such as high pressures or high temperatures has been challenging for several decades1,2. An illustrative example is the exploration of the negative-pressure regime that has vast implications for the understanding of diffusion processes in the micr...
Recently, it has been shown that a HE in an stationary state undergoing small perturbations of the energy exchanges with the surroundings obeys dynamical equations of the optimization time-variables. In that case, trajectories towards stationary state are not arbitrary and exhibit an optimization mechan...
