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 ...
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 ...
a(1) Flow stress increased quickly with increasing strain and reached a peak value when the strain was about 0.1, after which it decreased until it reached a steady value. this effect was attributed to the interaction between dynamic softening and work hardening during isothermal compression deforma...
The crystallization process of a Ti鈥揂l amorphous alloy during isothermal annealing was studied with molecular dynamics simulations. The structural development and phase transformation were analysed based on the variations of the internal energy, cell volume, radial distribution...
Using the first law of thermodynamics, explain why the total energy of an isolated system is always constant. Explain why the velocity of sound is greater in solids than in gases. It is unlikely that a process can be isothermal unless it is a very slow proc...
The internal oxidation formed during the advanced high-strength steels hot-rolled coiling process can be inherited into the cold-rolled sheet and impact the final product quality. Herein, the influence of Si on the internal oxidation and oxide scale phase transition behavior of Fe–Mn–Si advanced...
However, with a few exceptions, they have either assumed the process is completely isothermal or is a constant energy process. During coalescence, there is the formation of new bonds, decreasing potential energy, and correspondingly increasing internal kinetic (thermal) energy. Internal kinetic energy...
The influence of flow configuration on flame-wall interaction (FWI) of premixed flames within turbulent boundary layers has been investigated. Direct numerical simulations (DNS) of two different flow configurations for flames interacting with chemically inert isothermal and adiabatic walls in fully develope...
How, therefore, to characterize the stresses generated in the process of gas adsorption which are not explicitly included in the effective stress theory becomes the key of resolving this dilemma. The concept of adsorption stress or the internal stress induced by gas adsorption had been used to ...
During the pulping/delignification process, full or partial breakdown of the labile etheric linkages makes the native lignin structure more intractable. The resulting product is often termed as technical lignin e.g., Kraft/lignosulfonate lignin [1]. To avoid these changes in the lignin structure, ...
