WebbIn thermodynamics, a process is said to be reversible if it produces no entropy. This means that the process can happen in the reverse direction. Explain why the process described … Webb6 maj 2024 · First Law of Thermodynamics - The change in the energy of a system is the amount of energy added to the system minus the energy spent doing work. Second Law of Thermodynamics - It is impossible for a process to have as its sole result the transfer of heat from a cooler body to a hotter one. christian workers fellowship

WebbTo derive this process we start off by using what we know, and that is the first law of thermodynamics: ΔU = Q + W Rearranging this equation a bit we get: Q = ΔU + W Next, since pressure is equal to W ΔV, it can be denoted as: Q = ΔU + pΔV Now, the ideal gas law can be applied (PV=nRΔT) and since pressure is constant: Q = ΔU + nRΔT Webb27 apr. 2024 · Thermodynamics is considered fairly easy but this does not mean you can take it lightly.
